3 NAME AND FUNCTIONS OF EACH PART
Functions of Each Part
ICD Board
The ICD board is a hardware tool (emulator) to facilitate the efficiency of software development for the S1C17801.
It controls communication between your PC and the target IC (S1C17801) on the CPU board, providing simple
software development environments for S1C17801. For information about its functional difference from the ICD
Mini (S5U1C17001H), a development tool supporting all S1C17 core product models, see Chapter 6.
ICD Board Reset Switch
Pressing the reset switch (SW1) on the ICD board reboots firmware on the ICD board and outputs the target
reset signal (#RESET_OUT) to the CPU board. This establishes the communication connection between the
CPU board and the ICD board if they are physically connected. If the CPU board and the ICD board are not
connected physically, the communication connection becomes in the stand-by status.
ICD Board LED
The LED indicates ICD board and target statuses in different colors.
● (Blue) Power on (before the initial connection with the target is established.)
● (Green) The target is currently in debug mode.
● (Red) The target is not connected, or not properly connected.
The target is currently executing a user program.
CPU Board
The CPU board is a simple target evaluation board equipped with the target CPU (S1C17801). It is also equipped
with SRAM, NOR Flash, NAND Flash, EEPROM and other external memories,as well as peripheral functions and
circuits such as a LCD panel, RTC control circuit, MMC card, USB Audio IC, speaker, microphone, and remote
control emitting/receiving module, enabling the CPU board to be used for the development and evaluation of control software and other purpose.
CPU Board Reset Switch
Pressing the reset switch on the CPU board (S8 mounted on the rear face) resets the CPU board.
Coin Battery
A coin cell battery (of CR2032 standard) socket is mounted on the rear face of the CPU board. The socket is
used for power supply to RTCVDD.

(SOFTWARE EVALUATION TOOL FOR S1C17801)
5 OPERATING ENVIRONMENTS AND STARTING PROCEDURES
5 Operating Environments and Starting
Procedures
By connecting with your PC via the ICD board, the SVT17801 can be operated in accordance with commands executed by a debugger on the PC. The SVT17801 CPU board can be operated as stand-alone without using the ICD
board and PC. The following explains the connection and starting procedures required for each operation.
Software Simple Development Environments
The SVT17801 can provide simple development environments of software using the CPU board as a target. This
can be achieved by connecting the SVT17801 to your PC via the ICD board and using the S1C17 development tool
on the PC (such as GNU17 IDE, compiler and debugger included in the S5U1C17001C package).

Fig. 5.1.1 Software Simple Development Environments
Operation under Software Simple Development Environments
Under these operating environments,the target CPU (the S1C17801 on the CPU board) operates according to
commands executed by a debugger on your PC connected with the ICD board. A command executed by the
debugger is sent to the ICD board via USB to be analyzed and converted into a debug signal, and then sent
to the CPU board. The debugger on your PC can be used to download programs or data to the CPU board, or
debug programs by controlling their execution and stop.
Operating Mode of CPU
The "brk" command or debugging interrupts (such as forcible breaking operation by the debugger) from the
ICD board causes the target CPU (the S1C17801 on the CPU board) to stop executing the target program and
enter into debug mode (or break status). In this status, commands can be executed from the debugger on your
PC. LED on the ICD board lights in green during debug mode. On the other hand, the status where the target
CPU executes the target program is called normal mode. LED on the ICD board lights in red during normal
mode.
Connection and Start
The following describes connection and startup procedures to allow for the software simple development
environments.
(1) Connect the ICD board with the CPU board. Connect JICD 10 pin connector on the ICD board with the
counterpart on the CPU board. Then turn on the CPU board.

5 OPERATING ENVIRONMENTS AND STARTING PROCEDURES
(2) Turn on the PC (if it is turned off).
(3) Connect the evaluation board to your PC via a USB cable.
(4) When a screen appears on your PC prompting you to install USB driver, install an appropriate driver. This
operation is required only for the first connection. It is not required for the second connection and afterward. For the installation procedure, see the later section Installing USB driver .
(5) Make sure that LED on the ICD board lights in blue → green (the target is in debug mode).
(6) Start the debugger on your PC to execute the program. Make sure that LED on the ICD board lights in red (the
target is in normal mode).
For details on the operation of the debugger and debugging commands, see the S5U1C17001C Manual (S1C17
Family C Compiler Package).
Note: Be sure never to disconnect a USB cable between PC and ICD board while the debugger is running.
Installing the USB driver
(1) When the SVT17801 is connected with the host computer via USB cable, the following screen appears.
(2) Follow the wizard to install USB driver.
For brows directory of the USB driver, specify C:\EPSON\GNU17\utility\drv_usb.
∗ This indicates a directory path where IDE is installed.

5 OPERATING ENVIRONMENTS AND STARTING PROCEDURES
Standalone Operation of SVT17801
The SVT17801 CPU board can be operated as stand-alone without using the ICD board and PC.
Standalone Operation
In this operation environment, the S1C17801 on the CPU board operates in normal mode to execute a program
written in the built-in flash memory. Therefore, a user program must be downloaded previously to the flash
memory built in the S1C17801. (A demo-program is written in the flash memory of the SVT17801 as factory
default.)
For information about how to download a user program to the memory, see the "S5U1C17001C Manual (S1C17
Family C Compiler Package)."
Connection and Start
The following describes a method to operate the SVT17801 as standalone.
(1) Turn on the PC (if it is turned off).
(2) While the ICD board is connected with the CPU board, connect your PC to the ICD board via USB cable,
and turn on the CPU board.
(3) Start the debugger on your PC and download a user program to the flash memory built in the S1C17801.
For information about downloading a program, see the S5U1C17001C Manual (S1C17 Family C Compiler
Package).
(4) After exiting the debugger, remove the USB cable to disconnect the ICD board from your PC.
(5) Disconnect the ICD board from the CPU board, and install a coin cell battery.
(6) Press the reset switch on the CPU board. Then the S1C17801 on the CPU board starts executing a user program downloaded to the flash memory.
ICD Board Firmware Update Procedures
The SVT17801 can update the firmware of the ICD board using the debugger on your PC. The ICD board firmware
will be provided by EPSON if necessary. An update file has an .sa extension.)
The following describes firmware update procedures.
Note: USB driver must be installed before starting firmware update.
(1) Connect the evaluation board to your PC via a USB cable.
(2) Press the reset switch on the CPU board.
(3) Start the debugger from the command prompt.
>cd c:\EPSON\gnu17
(Specify the directory path where the gnu17 is installed.)
>gdb
(4) When the debugger starts, enter the following commands.
(gdb) target icd usb
(gdb) c17 firmupdate path\filename.sa
(where path\filename.sa is the update file name.)
(5) Finally, when the LED on the ICD board gets green(●), the firmware has been updated.
(6) Press the reset switch on the ICD board to reboot the firmware.

10 POWER CONTROL CIRCUIT FOR BATTERY BACKUP FUNCTION
10 Power Control Circuit for Battery
Backup Function
SVT17801 has a battery backup function, and is equipped with a power control circuit allowing for this function.
Battery Backup Function
Three power supply lines are available on the S1C17801, i.e., VDD, AVDD and RTCVDD. VDD covers CPU core, logic circuits, and I/O interface circuits, AVDD covers analog circuits (ADC), and RTCVDD covers RTC and IVRAM.
The battery backup function supplies power only to RTCVDD while stopping the power to AVDD and VDD. This
means that the function stops all operations except operating RTC and retaining contents inside IVRAM with low
power consumption. Because the power is supplied only to the minimum indispensable functions, leak current can
also be reduced drastically compared with sleep mode.
S1C17801
AVDD
VDD
RTCVDD
The SVT17801 is designed to connect the coin battery (CR2032) with RTCVDD, enabling RTC to keep functioning
and IRAM to retain its contents even if power supply from AC/DC adapter should be stopped.
In normal status, the power is supplied from AC/DC adapter without using the battery.
Power Control Circuit for Battery Backup Function
Figure 10.2.1 shows the power control circuit for SVT17801 battery backup function.

10 POWER CONTROL CIRCUIT FOR BATTERY BACKUP FUNCTION
#STBY Pin
This pin is used to disconnect the RTCVDD line from the VDD line (AVDD line) electrically.
If a LOW signal is input to the pin, area covered by the RTCVDD line becomes electrically independent of other
area. Stopping power supply to the VDD line (AVDD line) while a high signal is input causes inconstant signals
to be entered into RTC or IVRAM, or current to be leaked from the RTCVDD line to the VDD line. Therefore, be
sure to input a LOW signal to #STBY pin before stopping power supply to the VDD line (AVDD line).
∗ Notes: The RTCVDD area cannot be accessed while the #STBY pin is in LOW status. A HIGH signal must be
output from P43 to make the #STBY pin HIGH status before gaining access to the RTCVDD area.
WAKEUP Pin
This signal pin is used to restore the SVT17801 from battery backup status to normal status.
The VDD and AVDD lines can be turned on using the WAKEUP pin. For the SVT17801, this pin is connected to
the ENABLE pin on regulator,and so the power supply can be resumed by outputting a HIGH signal to the ENABLE pin.
The WAKEUP pin can be controlled by using RTC.
JP2 and JP3 Settings
In order to enable backup battery function on the circuit installed on SVT17801 as shown in the figure 10.2.1,
JP2 and JP3 must be set to WAKEUP ENABLE and Battery respectively (both factory default).
JP2 is located just before the WAKEUP pin s entering into an OR circuit, and if JP2 is set to WAKEUP DISABLE, 5V instead of WAKEUP pin is input to the OR circuit, turning regulator always ON.
JP3 selects supply source of RTCVDD shown in the figure 10.2.1. If Battery is selected, RTCVDD is supplied
from the coin cell battery (CR2032) and if VDD is selected, RTCVDD is supplied from VDD. For detail of JP settings, see Chapter 8.
RSTO (Power Switch) and WAKEUP Pin
The following list shows GPIO (PC2) status and VDD voltage according to power switch and WAKEUP pin
statuses when JP1 and JP2 are set to EnableWakeup and Battery respectively in the circuit shown in the figure
10.2.1.

➀ Set JP1 to EnableWakeup and turn the system power (VDD) on.
➁ CPU starts working.
➂ After setting P43 to HIGH output and the STBY pin to HIGH, set WAKEUP to HIGH active and
WAKEUP output signal to HIGH. (to enable WAKEUP status)
•••
➃ Press power switch. (Pressing the power switch turns PC2 HIGH.)
➄ If PC2 s HIGH status is detected, set P43 to HIGH output and the STBY pin to HIGH (to enable write
to IVRAM inside RTC).
➅ Write RTC setting data to IVRAM.

➆ Set the WAKEUP signal to LOW. → ∗ The power switch is being pressed during above steps.
➇ Setting for standby mode has been completed. (RTCVDD is running in ON status.)
After ➇, the VDD line (AVDD line) can be turned off.
Releasing Standby Mode
The following is an example to show how to release standby mode in the circuit shown in the figure 10.2.1.
(Example 1)
➀ In Step ➄ of above set-up example 1, the standby mode is released (WAKEUP pin is turned HIGH) after predefined time has passed, and the output of regulator shown in figure 10.2.1 becomes always 3.3V.
(Example 2)
➀ Press power switch.
➁ While the power switch is being pressed, the output of regulator shown in figure 10.2.1 becomes 3.3V,
S1C17801 starts operating and, immediately after that, the standby mode is released by turning the
WAKEUP signal HIGH.
➂ By turning the WAKEUP signal HIGH at Step ➁, the output of regulator shown in figure 10.2.1 becomes always 3.3V.
∗ This power control circuit should be used only for reference. The circuit is designed for reducing the current consumption of whole system by turning the VDD line (AVDD line) off. This technique is effective for the case where
the VDD line (AVDD line) has a longer power-off time, or a board has many peripheral parts with relatively HIGH
current consumption. Other technique (such as Sleep or Halt) may still be advantageous depending on your approach to control the overall system. We recommend you review all necessary factors to choose the optimal way
when you design a total system.

In order to obtain panel s touch position information on X-axis of the figure 11.1.2, an AD value obtained from
AIN6 is used to determine the position of X-axis when P33 is turned LOW while P34 HIGH as shown in X-axis
fields shown in the table 11.1.1. (The AIN6 value becomes gradually larger for the left side of the figure 11.1.2.)
On the other hand, to obtain panel s touch position information on the Y-axis of the figure 11.1.2, an AD value obtained from AIN5 is used to determine the position of Y-axis when P33 is turned HIGH while P34 LOW as shown
in Y-axis fields of table 11.1.1. (The AIN6 value becomes gradually larger for the upper side of the figure 11.1.2.)
This principle to obtain X-axis and Y-axis data helps acquire two-dimensional touch position information by obtaining X-axis and Y-axis AD values while alternately switching between P33 and P34 statuses with a short duration.

Fig. 12.1 Key Input Connection Circuit on CPU Board
In this circuit, the press of a switch is detected by the port (P31) status and the pressed switch is determined by
detecting an input value of AD (AIN7).
The mechanism of detecting the switch status by the port (P31) status is as follows: If all switches are open, the
port (P31) is in HIGH state as it is pulled up by the 35.7KΩ resistor (5.1KΩ x 7) as shown in the figure 12.1. If
any of the switches is pressed, on the other hand, the pull-down resistor value becomes smaller than the pull-up
resistor value, and this turns the port (P31) LOW. The mechanism of this circuit enables the press of any switch to
be detected by using interrupt or other method.
Figure 12.1 also indicates that the pressed switch can be determined by the variance of ratio between the pullup resistance value and the pull-down resistance value, because the ratio changes depending on the switch being
pressed. The change can be detected by an AD (AIN7) input value. Figure 12.2 shows the equivalent circuit of the
figure 12.1.
AVDD
The following equation is satisfied in this equivalent circuit:
V = R2/(R1+R2)×AVDD
R1
V
R2
"V" value for each switch is obtained by resistance values of R1 and
R2 that are obtained when the switch is pressed. Thus the pressed
switch can be determined by comparing the "V" value with the value
actually entered into AD (AIN7).

Rotating the rotary encoder closes the A and B switches shown above, and the time difference of switching occurs
depending on the rotative direction. When the encoder does not rotate, both of two ports connected to the S1C17801
are pulled up to HIGH. When the encoder rotates, on the contrary, they are turned LOW, and phase difference arises
between the HIGH and LOW timings of those ports. The phase difference can be detected by software to govern
the rotative direction. As a switch is directly connected to a port, pressing the switch turns the port LOW. The LOW
zone can be detected by software.

19 AUDIO CONNECTION CIRCUIT
19 Audio Connection Circuit
The SVT17801 is equipped with a 16-bit AudioCodec (TI model PCM3793). SVT17801 circuit related to the
AudioCodec is shown in the following diagram.
The SVT17801 connects the S1C17801 and the PCM3793 using I2C and I2S. I2C is used for the communication
of audio setup commands issued from the S1C17801 to the PCM3793. Two channels of I2S are available for
the S1C17801, i.e., Ch0 (signal name: I2S_***0) and Ch1 (signal name: I2S_***1), used for output and input
respectively.
Switching Audio Master Clock
The SVT17801 can switch the master clock for the PCM3793 between that from I2S_MCLK0 on the S1C17801
and that from an external transmitter. Specifically, either of the master clocks can be selected using a switch IC
connected to P32. Following table describes how the switching is possible.

20 Exclusive Control of Ports
The SVT17801 uses five ports exclusively by connecting them to switch ICs as shown in the following. As a result,
the following combination cannot be operated simultaneously.
(1) Write to NAND Flash and the control of LCD touch panel.
(2) Write to NAND Flash and the control of power switch using standby.
(3) Write to NAND Flash and the control of 7th pin/9th pin on J8 connector.
Specifically, the five ports are used exclusively by switching H/L of P45 as shown in the following table.

Appendix A HOW TO MEASURE CURRENT CONSUMPTION
Appendix A How to Measure Current
Consumption
For measuring current consumption of the single S1C17801 unit, jumpers (JP4,JP5,JP2) are available on the
SVT17801 CPU board. The S1C17801 has three power supplies, one for core and I/O (VDD), one for analog system
(AVDD), and the other for RTC (RTCVDD). Jumpers are available for each power supply. Current consumed by each
power supply line can be measured by inserting an ammeter among the pins after removing the jumper. Sum of the
current obtained from each power line is current consumed by the single S1C17801 unit.
A.1 Measuring VDD Current Consumption
Current consumed by the power supply for core and I/O (VDD) can be measured by inserting an ammeter into JP4.
Because external components affect the measurement, some necessary process is required for each I/O pin. To
measure current consumption for the single S1C17801 as described in the S1C17801 Technical Manual, influence
by current must be controlled for "USB pins" and "STBY pins."
For information about sample software (software flow) to measure current consumption, see the S1C17801 Current
Consumption Measurement Application Note.
∗ USB Pins
Shot key diodes D3 to D6 are attached to the SVT17801 USB pins as shown in the figure A.1. The diodes attachment is intended for electrostatic protection. However, current flowing through the diodes is also measured when
measuring Halt or Sleep current of the single S1C17801, and this diodes current causes deviation of the single
S1C17801 current consumption from that described in the S1C17801 Technical Manual.

If each USB pin is in the following state,
• as shown in the figure A.1.,
• N.C. for each of the USB pins (D3 to D6, C51,C24,R53,C21,R25,R52,R22,R23 not installed)
Current consumption differential for VDD line is approximately 100 μA.
∗ STBY Pins
The STBY pin on the SVT17801 can be controlled by GPIO(P43) as shown in the figure A.2, and pulled down
by the resistor R21 (10KΩ). The following current flows if P43 is in HIGH output state.
IR21 = 3.3(V) / 10(kΩ) = 330(μA)
(if VDD = 3.3V)
To reduce current consumption in Halt or Sleep mode, set P43 to the LOW output port. Then this current is
cancelled. However, note that executing this operation while OSCI is used as a system clock causes system to halt

Appendix A HOW TO MEASURE CURRENT CONSUMPTION
until being reset.
When this circuit is actually used for your circuit, a proper pull-down resistance value must be selected because the
value affects the current consumption of total system.
(When R21 = 100KΩ IR21= 33 μA approx., and when R21 = 500KΩ R21 = 6.6 μA approx.)
If you do not use battery backup function, input RTCVDD to #STBY.

A.2 Measuring AVDD Current Consumption
Current consumed by the power supply for ADC (AVDD) can be measured by inserting an ammeter into JP5.
Note that sample software (software flow) for measuring the current consumption, the software referred in the
S1C17801 Current Consumption Measurement Application Note does not control the AVDD line.
A.3 Measuring RTCVDD Current Consumption
Current consumed by the power supply for IVRAM and RTC inside battery backup area (RTCVDD) can be
measured by inserting an ammeter into JP2.
When JP2 is measured between 2-3 pins, the voltage becomes 3.3V because RTCVDD is supplied from VDD
generated by regulator. When JP2 is measured between 1-2 pins, on the other hand, the voltage becomes 3.0V
because RTCVDD is supplied from coin cell battery.
Note that sample software (software flow) for measuring the current consumption, the software referred in the
S1C17801 Current Consumption Measurement Application Note causes approximately 3 to 4 μA current to flow in
the RTCVDD line.
