contents to FFH (00H for P89LPC9xx family) whenever you load a new
file into the buffer. This option should be disabled before loading multiple
files to a single buffer. Otherwise, this option will clear the buffer contents
when loading each file to buffer.
The second option “Clear Buffer for new device selection” clears the
buffer contents after the selection of a new device.
OTP devices will not have the option of erasing the device. In this case,
the option, “Erasing the device before Programming” will be disabled.
The programming option will come into effect when the mode of
programming is normal and not in Auto Programming Mode. When you
enable this option, every time when you program the device, the device

5.1. Introduction:
The programmer maintains a buffer area equivalent to target controller’s
flash memory area, Program Encryption Table, User Parameter Table
and Target serial EEPROM area. Keeping your program code or data
inside of the respective buffer, you can edit, modify as per your
requirement before programming. You can also incorporate changes in
your target program code without going back to the original development
tools thanks to the built-in assembling facility. This is one important facility
required during field up-gradation of the finished applications.
5.2. Types of Programming Data:
You can load any specific buffer with the program/ data from any file.
Program can be loaded in both Intel Hex and Binary formats. The
programming code can be loaded from any file to any specific buffer or
to many buffers at the same time using both of these formats.
In the Intel Hex format, the information on address of the locations comes
in the file itself. In Binary format, you need to Key in respective address
during buffer operations.
Following are the types of programming code/ data handled by the device
programmer:
One Time Programmable ROM with Program Encryption Table.
One Time Programmable ROM with User Parameter Table.
Flash memory area.
21
Topview Programmer A
Software User Guide
Chapter 5: Programming Environment
5.2.1. OTP ROM with Program Encryption Table:
The OTP devices of the Philips microcontrollers except P87LPC76X have
OTP memory area to store Program code and 32 / 64 bytes of Program
Encryption Table.
The OTP memory starts from 0000H and the ending address varies
according to the device capacity. The address of the Program Encryption
Table starts from the next address after OTP area.
For an example, in P87C51, the OTP memory of 4K starts from 0000H to
0FFFH and the Program Encryption Table is available from 1000H to
103FH. When you load the buffer meant for this device using the file, all
the program code between 0000H and 0FFFH is transferred to the flash
buffer and the data between 1000H and 103FH will be made available in
the buffer of Program Encryption Table.
Similarly during file storage operation, contents of all the buffers will be
stored in the respective memory location meant for that selected
microcontroller.
5.2.2. OTP ROM with User Parameter Table:
The P87LPC76X family devices have OTP ROM and 32 bytes of User
Parameter Table.
The program memory address starts from 0000H.
The ending address depends upon the capacity of the selected device.
The actual physical address of User Parameter Table lies between FCE0H
and FCFFH.
In Hex file format, the actual address of the User Parameter Table is
22
Topview Programmer A
Software User Guide
Chapter 5: Programming Environment
always defined as the one from FCE0H to FCFFH. When using binary
format, the actual address is mapped to the location immediately after
the program memory space.
As an example, consider the device, P87LPC760, which has 1K Bytes of
program memory and 32 bytes of User Parameter Table.
For Intel Hex format:
Program Memory
:
0000H to 03FFH.
User Parameter Table
:
FCE0H to FCFFH.
User Configuration Register 1
:
FD00H.
User Configuration Register 2
:
FD01H.
When you use Binary file format:
Program Memory
:
0000H to 03FFH.
User Parameter Table
:
0400H to 041FH.
User Configuration Register 1
:
0420H.
User Configuration Register 2
:
0421H.
During buffer storing and loading operations, respective memory areas
are properly saved or read from the files automatically.
5.2.3. Flash Memory Area:
Normally flash memory of any microcontroller is mapped into the program
memory space. Most of the time, this memory contains only programming
code along with required data.
23
Topview Programmer A
Software User Guide
Chapter 5: Programming Environment
5.3. Device Project File:
The programmer gives you the facility to keep all the relevant program
and data information generated for the specific device in an exclusive
project file. So, you need not worry about keeping flash memory, User
Parameter Table and Program Encryption Table at their respective
address blocks.
You can easily save device project file and load the same from files using
simple commands.
5.4. Buffer Operation:
The programming environment sports few buffers, which play an important
role during programming.
Available Buffers are:
Flash Buffer.
Program Encryption Table Buffer.
User Parameter Table Buffer.
EEPROM Buffer for serial EEPROM device.
5.4.1. Flash Buffer:
Normally, the buffer space will be made equal to the size of the selected
device’s flash memory capacity.
For an example, for the device P89C51, the buffer space goes up to 4K
(0FFFH). If the target file exceeds this space, an error message will be
24
Topview Programmer A
Software User Guide
Chapter 5: Programming Environment
duly displayed for your convenience.
During programming, you may want to load your target program file into
this buffer space and then you may modify / correct the contents as per
your needs.
For your convenience, the buffer provides a “Single line Assembler” to
carry out these modifications with ease and confidence.
Another facility is, the buffer helps you to keep programming data from
many files in order. You can load these files into the buffer and verify the
whole lot and then program the target device in a single shot.
Buffer supports editing (In both Hex and ASCII), locating a byte, clearing,
filling, copying operation and also generates a checksum. All these
operations are explained in the detail in subsequent pages.
Another interesting facility using different colours is made available in
the buffer to indicate certain operations.
Normally the buffer contents are displayed in the black color. When a file
is loaded into the buffer, the colour changes to blue.
When you carry out editing in the contents of the buffer, the edited portion
is displayed in red colour. When you load the buffer from the flash area
of the selected device, that portion is displayed in green.
So with a little experience on the usage of different colours for buffer
functions, the colouring will assist you very much during program
development / debugging.
The buffer also sports a disassembly facility. When you activate this,
contents of the buffer will be displayed as program rather than as data
and you can see the actual program code in mnemonics. At this stage,
25
Topview Programmer A
Software User Guide
Chapter 5: Programming Environment
you can edit your program code or insert new program lines using built-in
single line assembler.
5.4.2. Program Encryption Table Buffer:
For some OTP devices, Philips provides a Program Encryption Table of
64/32 bytes in length.
A separate buffer is made available for this table. Like flash buffer, this
also has all the features except the disassembly facility since it contains
only data.
5.4.3. User Parameter Table Buffer:
In P87LPC76X family of controllers, this is an area of 32 bytes in the
memory meant for keeping User Parameter Table. This User Parameter
Table lies between FCE0H and FCFFH.
An exclusive buffer is made available for this table.
Like other buffers, this has all the features except the disassembly facility.
5.4.4. EEPROM Buffer for Serial EEPROM Devices:
Depends upon the selected EEPROM device, a suitable buffer area is
available during programming operations.

7.1. Introduction:
Many Microcontrollers from Philips have the facility to get programmed
even after soldered in the target board. You need not remove the device
from the PCB for programming purpose. This is very much required when
you use SMD devices in your applications. These controllers have In
System Programming and In Circuit Programming facilities to enable you
to update target application in the field and use the same hardware in
different applications by varying the software. If you provide a simple
connector in your target hardware, you can upgrade/change the target
programming code using Topview Programmer A.
7.2. ICP and ISP Modes:
Philips Semiconductor has made different modes of programming
available in many of the microcontrollers to enable the user get versatile
up-gradation facility in his/her applications.
In System Programming (ISP).
In Circuit Programming (ICP).
In Application Programming (IAP).
Parallel Programming.
These microcontrollers come with all required hardware and software
resources to program flash memory area when the devices are properly
initialized. The device takes care of complicated timing requirements all
by itself along with the programming software kept at the higher location.
ISP mode uses the serial port of the device for programming and you
can program the flash memory area keeping the controller mounted in
the target hardware. The device can be programmed with the application
code without removing the device from the PCB. Also all the programming

functions are available. A previously programmed device can be erased
and reprogrammed. Since these devices come with non-erasable built-in
subroutines located in ROM area, you can easily download your
application code through the serial port by calling relevant routines.
To incorporate this ISP facility in your hardware, you need to keep a
connector exclusively meant for this in your hardware. The ISP function
uses five pins: TXD, RXD, VSS, VCC and VPP. The basic circuit required

The ISP mode is closely associated with the Boot ROM which contains
the programming routines, and special registers, Status Byte / Bit and
Boot Vector.
You are going to see how to use this ISP mode effectively in the coming
paragraphs.
ICP mode is almost similar to ISP except it does not use the device’s
serial port for communication. It uses two port I/O lines for communicating
with the host system.

Chapter 7. Programming the Soldered Device in the Target Hardware
IAP mode is for embedding the on chip programming facility in your target application. You may include this in your application to provide a kind
of self-upgradation facility or to get latest calibration information and etc.
You need to refer the Philips Documentation to know more on this IAP
mode and such a discussion is beyond the scope of this manual.
Topview Device Programmer A has required facility to program these
microcontrollers in Parallel Mode. You may use this Parallel Programming
facility to restore the Boot ROM in the device after it is erased.
7.3. Power on Reset Code Execution:
The controllers (with ISP facility) contain a Special flash Register, Status
Byte which indicates the starting address of the program code. At the
falling edge of reset, the controller examines the Status Byte and if the
Status Byte is set to zero, power up execution starts at location 0000H,
which is the normal start address of user application code. When the
Status Byte is set to a value other than zero, the factory masked ROM
ISP Boot loader is invoked. The factory default for the Status Byte is
FFH. Once set to 00H, the Status Byte only be changed back to FFH by
a full chip erasing when using ISP.
7.4. Hardware Activate of the Boot Loader:
The microcontroller’s Boot Loader can also be executed by holding PSEN
low, EA grater than VIH (such as +5V) and ALE high (or not connected)
at the falling edge of Reset. This is same effect as having a nonzero
Status Byte. This allows an application to be built that will normally
execute the end user ’s code but can be manually forced into ISP
operation.

Chapter 7. Programming the Soldered Device in the Target Hardware
After programming the flash, the Status Byte should be programmed to
zero in order to allow execution of the user application code beginning at
0000H.
7.5. Boot ROM:
When the microcontroller program its flash memory during ISP, all of the
low-level details are handled by the code contained in 1K Byte Boot ROM.
The size of the Boot ROM varies from device to device. Boot ROM
operations include: Erase Block, Program Byte, Verify Byte, Program
Security Bit etc. The Boot ROM area is mostly located at the address
FC00H- FFFFH in a non erasable masked ROM.
7.6. Status Byte/Bit:
The Status Byte is located in the programmable flash memory. After
Reset, the microcontroller checks the Status Byte.
If the Status Byte is 0, the program begins executing from address 0000H.
If the Status Byte is not 0 (FFH is preferred), the program jumps to the
address pointed to by the Boot Vector. The pointed address is the
beginning of the ISP code.
After programming the flash memory, the Status Byte should be erased
to 00H in order to allow the execution user ’s code beginning at address
0000H.
Some devices may have the Status Byte and some may sport Status Bit.

7.7. Boot Vector:
The Boot Vector is located in the flash memory.
After Reset, the program jumps to the address pointed to by the Boot
Vector. The ISP program usually located at address FC00H. So, the Boot
Vector contains the address, ‘FC00H’. Do not change this, unless an ISP
program is located elsewhere.
After programming your application code in the flash area, you have to
program the Boot Vector to the Boot ROM starting address, FC00H and
the Status Byte to zero to enable the ISP programming.

7.8. Basic Requirements in Target Hardware to get ISP facility:
The hardware should have an on board oscillator. The serial port lines
RXD, TXD, PSEN, and Reset lines should be isolated from the application
during programming. You can introduce a jumper setting as shown here
to get this arrangement.

For normal operation, connect pins 1 and 2 and to program the device
connect pins 2 and 3.
The Vcc and EA/ Vpp pins should be kept at +5V.
7.9. Connecting the Target Hardware to the Programmer:
To program the device using ISP, a 10 pin connector (CON 3) is provided
in the Topview Programmer PCB at the right side top corner. Connect
this connector to the target as shown here:

programming. The specified pins of the device should be properly isolated
from the rest of the circuit during programming. Otherwise, damage may
occur to the controller as well as to rest of the circuits.
For P87LPC76X devices, if the Vpp pin is not isolated from other circuits
in the target hardware, the high voltage, 10.75V delivered from the
programmer may damage your target. Connect the programmer to this
target hardware through the ICP/ISP cable provided along with the
programmer.
