In addition to Standard (non-Split) printing mode, latchless Split-printing mode and latchless two-clock mode can be supported. The three signals PDAT, PCLK, and PLAT control the transfer of data to the printer.

3) Scanner Control.

Four programmable control and timing signals supports CIS scanner interface. An internal 8-bit

A/D converter is provided. Video processing supports DLC and two modes of shading correction for scanner data non-uniformity’s arising from uneven sensor output or uneven illumination.

Correction may be provided to an 8-pixel group at a time or, separately to each pixel. Less than 1

K of RAM is required to support shading correction. A Digital Adaptive Halftone image processing is supported. A 2-Dimensional error diffusion algorithm as well as a 2-D Edge Enhancement control are performed in the hardware. Dynamic background and contrast control is provided for text images. Multi-level horizontal B4 to A4 reduction is also provided for the scanner data.

4) Motor Control.

Eight outputs are provided to external current drivers; four for scanner motor.

5) Image Coding Schemes.

FC200 (-M) provides MMR data compression and decompression conformed with ITU-T recommendation T.4.

6) Real Time Clock (RTC).

FC200 (-M) includes a battery backed-up real time clock. The life of the RTC is 32 years, and leap year compensation is automatic.

7) External Memory Support.

External ROM stores the program object code. External RAM is used by processor for shading correction and line buffer. DRAM controller supports refresh during battery operation. DRAM stores image and voice data.

6-1

8) Modem Interface.

FC200 (-M) runs at a clock derived from modem clock. FC200 (-M) immediately handles interrupt request from modem in order to keep constant transmission flow.

9) Panel Interface.

Four inputs, eight strobe outputs, and two control outputs support keys scan and LCD driver.

10) Battery and Power.

FC200 (-M) detects power failure and switches to battery backed-up mode.

6.1.2.1. Bus Cycle Timing

The processor and external bus cycle timing is defined by bclk (an internal signal). bclk is referenced to TSTCLK which is derived by dividing SYSCLK by either 2 or 3,as shown in Figure

8.1.1.1-1 and Figure 8.1.1.1-2,respectively. bclk can be extended low (halted state) or stretched high (wait state) by external and internal conditions that are described later. Both halt and wait state are indicated on the external pin WAITn.

A standard bus cycle begins at the falling edge of TSTCLK and ends at the falling edge of the next

TSTCLK. Some memory and peripheral devices require extended bus cycle, which is accomplished by adding wait states. During wait states, the WAITn signal is activated. Wait states can be created with programmable control provided for external chip selects (ROMCSn, MCSn, CS [5:0]n), by the

DRAM controller (CAS[1:0]n),and with the external RDY input pin. The wait states created by the

RDY input are added to the wait states generated by the chip select control logic.

The bus cycle can be halted by BE pin or by an access conflict (i.e., a CPU or DMA access to

DRAM coincident with a DRAM refresh, or a CPU access to the RAM when a DMA access of the same RAM is in progress). When the bus cycle is stopped, Halt states are added in increments of 1

TSTCLK. When the Halt condition is released, the bus cycle resumes at the next TSTCLK rising edge Figure 6-2 shows an example of a bus cycle with 1Halt state.

6.1.2.3. DRAM Controller

The DRAM chip provided is 1 Mega by 4 bits with maximum access time 100ns. Up to 1 column chip selects, /CAS0, are supported to access total 1 Mega bytes. For basic memory of 1Mega bytes,

2 DRAM chips are provided, while for extended memory, 2 more chips are provided.

Address bus of DRAM are physically connected to address bit A0 to A9 of FC200(-M). Row addresses are gated onto the DRAM address bus first, followed by column addresses. The following operation modes are supported: bytes access mode, early write mode and normal read mode. One wait state is inserted in each DRAM bus cycle.

DRAM refresh is performed automatically, but only /CAS before /RAS operation is supported.

Refresh cycle time per 1024 cycles is 125ms. During power on when it is time to refresh DRAM and they are not being accessed, the refresh cycle starts. When power down, no DRAM access occur, and DRAM can’t backup the data.

6.1.2.4. CPU Interrupts

There are two ways to interrupt CPU, maskable interrupt (/MIRQ) and non-maskable interrupt NMI

(/DEBUG,/PWRDWN). Modem interrupt /MIRQ must hold active until the CPU processes the request. The input /PWRDWN is OR'ed with the input /DEBUG and then synchronized before NMI input. An active NMI signal branches program execution to the address stored in NMI vector. When

NMI represents power down, indicated by /PWRDWN low, the NMI control firmware performs the necessary maintenance operation and then enable lockout register to protect battery backed-up

registers during power down.

6.1.2.5. RESET logic and Watchdog Timer

There are two power resets, battery power reset (/BATRST) and prime power reset (/PWRDWN).

The battery power reset initializes battery backed-up logic when battery is first applied or changed.

Prime power reset initializes all non-battery powered logic when system power is turned on.

Another reset is generated by watchdog timer which guards against firmware lockup. /RESET pin provides a reset signal to external devices when power down or watchdog reset is active. If

/BATRST become low, D2 ON, sothet U2C Op output low and reset modem.

6.1.2.6. Real Time Clock

The Real Time Clock (RTC) circuit is required to maintain current time information under primary power and battery backup conditions. RTC tracks seconds, minutes, hours, days, months and years elapsed since the reference year, 1999. The tracking range of RTC is up to 32 years, and automatic compensation is made for leap years.

6.1.3 Scanner Controller

Only one type of scanner can be applied, Hualing. Power of scanner LED is on/off controlled by transistor switch Q1 and Q2. CLK2 is 500KHz clock to scanner and START is periodic pulse for every 10ms. The scanner outputs video signal synchronized to clock. A flash A/D converter in

FC200(-M) samples the video signal. FC200(-M) performs shading correction to correct scanner data for non-uniformity of 1728 image sensors. State of art image processing on both text and halftone images are provided. Edge enhancement improves image quality on halftone, and dynamic contrast control improves text image. An internal dither table programmable up to 8X8 byte matrix is provided to perform halftone process.

The video signal is amplified by adaptive gain in order to let white video level close to reference level of flash A/D converter.

6.1.4 Motor Drivers

Signal SM[0..3] are selected as scanner control lines. The stepping pattern signals determined by firmware outputs to scanner motor via current drivers, transistor array.

6.1.5 Switch and Sensors

Cover on/off switch is debounced by a RC couple. Paper sensor output is shunt by a noise-filtering capacitor.

6.1.6 Battery and Power Down Reset

Prime power failure is detected by a voltage comparator that compares +5V supply with a constant reference voltage 4.5V provided by transistor voltage source.

Battery BT1 backs up VXFC, and SRAM in the beginning of power down.

6.1.7 Fax Modem Circuit

The Rockwell R96DFXL MONOFAX modem is a synchronous 9600 bits per second (bps) halfduplex modem with error detection and DTMF reception. The modem can operate over the public switched telephone network (PSTN) through line terminations provided by a data access arrangement (DAA). The R96DFXL is designed for use in Group 3 facsimile machines. The modem satisfies the requirement specified in CCITT recommendations V.29, V.27 ter, V.21 Channel in 2, and T.4, and meets the binary signaling requirements of T.30. The pin assignments for 100-pin

PQFP are listed in table 8.1.7-1, and its digital interface characteristics is listed in table 8.1.7-2, analog interface is listed in table 8.1.7-3.

6-18

6.6.3 Ringing

The ring signal is checked at pin FCI (U1 pin 21) for a valid ringing frequency. As soon as a signal is applied to the line, the internal ring frequency detector will start, provided that the signal level at

FCI is above the trigger threshold (~2/3 V

DD

). If the frequency is within the specified range(15~80Hz), the melody generator will send a bitstream out of MO (U1 pin 8), charging the piezo ringer via Q14 and discharging it via D17 and the internal high voltage open drain transistor.

As soon as a non-valid or missing ring signal is detected, the bitstream is stopped and the circuit returns to standby.

(Ringer supply)

6.6.4 DTMF Dialling

During DTMF dialing the same line conditions as in Speech mode apply, except that speech is muted in both directions and a confidence tone is sent to the Rx amplifier. The DTMF signal is modulated to the line by controlling the shunt transistor, Q8. During inter-digit pauses speech is also muted.

DTMF level is adjusted by a DC voltage at the MFL (U1 pin2) input. This voltage is set by a voltage divider (R40, r41), connected from AGND to V

SS

.

The DTMF timing is set by D15 and D16. The pulse time/pause time is 82/160ms with D15, and

82/82ms with D16.

6.6.5 Pulse Dialling

With pulse dialing, the line has to be interrupted during break periods and short circuit during make periods.

Break pulses are performed by Q5 being switched off. The on-off control signal is output from the

HS/DP (U1 pin 10) switching Q7 (and in turn Q5) on and off.

Make pulses are performed by Q8 with Q5 being switched on. The base of Q8 (CS, U1 pin25) is pulled to V

SS

.

Make/Break ratio is set by JP18 and JP19. The make time is 40ms with JP18 and 33ms with JP19.

6.6.6 Speech mode

6.6.6.1. Transmit

The electric handset microphone is supplied from the constant voltage at U1 pin27 (LI), filtered by

R31 and C27. R32 and R33 are the bias resistors of the electric microphone. Transmit gain is set by both selecting the proper microphone type (sensitivity) and by varying R32 and R33.

Transmit frequency shaping can be done by C24, C25 (high pass) and C21 (low pass). R35 can be installed to attenuate the microphone signal without affecting the frequency response curve. Pin23

(M1) and pin24 (M2) are differential input of the microphone amplifier. Please note the proper connection of the M1 and M2 inputs in respect to the positive and negative side of the microphone.

6.6.6.2. Receive

Receive gain is set by both sensitivity of receiver and the value of R36.

Receive frequency shaping is done by C29 (low pass) and C28 (high pass). R36 is to attenuate the receiving signal.
