CHAPTER 1 GERERAL DESCRIPTION
Genesys Logic's single-chip GL848 (GeneScanTM series) is a high speed, high performance and rich scalability controller for scanner with fast ADF function and bus power. It successfully integrates scanner function ASIC and USB 2.0 interface controller into one single-chip. With its high performance design architecture, GL848 is not only ready for supporting CIS or CCD image sensors (600, 1200, 2400, 3200, 3600, 4800 and 9600dpi resolution) that are used in sheet-fed, flatbed or transparency scanners, but is able to co-work with unipolar or bipolar stepping motors. Advanced features of GL848 include five motor acceleration/ deceleration curve tables for high speed motor moving.

It's for carriage to go home automatically after scanning finished. Turn off MOTOR power and phase to idle state. Turn on MOTOR power and phase. Move to scanning window by only one acceleration/deceleration tables. Move to scanning window by two acceleration/deceleration tables. Set motor to move in forward direction. Set motor to move in reverse direction. Motor will be decelerated when home sensor input (HOME) changes from low to high (rising edge). Motor will be decelerated when home sensor input (HOME) changes from high to low (falling edge). The deceleration curve of the fast moving is defined in table 4 or use default curve. The deceleration curve of the fast moving is defined in table 5 to protect wall-hitting.

PWM Duty Frequency
Phase on time
22 Watchdog Protection
This function can automatically reset the system to initial state when the system is hanged (no access signal) beyond the time limit. It can be enabled or disabled by S/W. This function can protect motor power, lamp power and ASIC system. Calculation formula: (30sec.) * (times setting) * (setting number.). The range of setting number is from 1 to 15; the range of times setting is 0 or 1.
23 Lamp Time-out Control
This circuitry can automatically turn off the lamp power when this function is enabled. It can be enabled or disabled by S/W. Calculation formula: (60sec.) * (times setting) * (setting number). The range of setting number is from 1 to 7;the range of times setting is 0 to 3.
24 Lamp Power Control
These are two power control ports for lamp. One is for Flatbed and the other is for XPA (Transparency or film). These control ports have PWM function. According to the system clock, designers can flexibly adjust their frequency and duty by S/W. And the resolution of PWM is 16 bits.
25 Sensors
The system supports home sensor for flatbed; ADF sensor, document sensor and cover sensor for ADF module.
26 GPIO Ports
Designers can separately assign input or output direction for each GPIO pin of GPIO1~21. Some GPIO can be designed for keypads or motor power control...etc. Note : There are four pins for special function. GPIO9: This pin can control bipolar motor driver IC (2916,6219 or 3967) Vref3 for control Imax current. GPIO13: This pin can control bipolar motor driver IC (2916,6219 or 3967) Vref2 for control

Imax current. GPIO12: 1. Pull up by resistor to indicate ASIC to turn on lamp power in power-on initial state. 2. Pull down by resistor to indicate ASIC to turn off lamp power in power-on initial state.. 3. This pin can control bipolar motor driver IC (2916,6219 or 3967) Vref1 for controlling Imax current. GPIO11: This pin can control bipolar motor driver IC (2916,6219 or 3967) Vref0 for control Imax current.
27 GPO28, 31~34 Ports
GL848 provides 5 ports for general-purpose output. They are multi-functions.
28 Power on Check
The default status of the PWRBIT control bit is reset. Programmers can set the PWRBIT control bit before controlling the ASIC. GL848 will keep the status until power is turn off. This operation is to check if the power had been turned off or not.
30 LED Blinking
GL848 supports LED -blinking function. It is implemented in GPIO8~10 and GPIO21.
31 Support Back Scanning
GL848 supports forward or backward scanning.
32 Supports ADF Function
GL848 supports ADF (Auto-document-feeder) function via internal logic circuitry. Programmers need to set the ADFSEL control bit to logic `1'. GPIO6 controls the motor pulse trigger if the motor moving of ADF module is implemented by trigger pulse, otherwise the motor moving is driven by motor phases. GPO28 controls the moving direction of motor if ADF module is necessary. GPIO16 is the cover sensor input, ADF_SENR is the ADF sensor input and HOME is document sensor input under ADF mode. Scanning Window
Document Sheet
Document Sensor
ADF Sensor PREFED
GL848 can feed document sheets automatically to scanning window. After sensing the present of document by document sensor, software should issue feed command to GL848 for paper feeding. After document sheet reaches ADF sensor, scanning process will be started after PREFED motor steps.

PSTFED
When document sheet keeps moving forward, after sensing the absent of document by ADF sensor, scanning process will be terminated after PSTFED scanning lines.
33 Supports RS232 Interface
GL848 supports RS232 interface via internal logic circuitry. Programmers need to set the RS232SEL control bit to logic `1'. GPIO6 transmits the data of RS232 and GPIO28 receives the data of RS232 under RS232 mode. The baud rate can be programmed to 2400,4800, 9600 and 19200 bps by S/W.
34 Supports EEPROM (93C46) Interface
GL848 supports EEPROM interface via internal firmware. GPIO6 controls SK of external EEPROM, GPIO5 controls DI/DO of EEPROM and GPIO7 controls CS of external EEPROM.
36 "True gray" with R,G and B weightings
Designers can obtain the "true gray" image data by enabling "true gray" function. Image data is generated by R,G and B outputs and multiplied by weightings. Formula of true gray value = R*(TRUER [7:0]) + G*(TRUEG [7:0]) + B*(TRUEB [7:0])
38 Lines Packing for Stagger CCD or R/G/B Line Differences
GL848 packs R, G and B lines together for CCD sensors by hardware. And it also packs the same color lines of stagger CCD together.
39 Fine CDS Sampling Adjustment
Designers can fine-tune the CDS sampling position to avoid the digital noise influence (8.33ns adjustment). The image noise may come from the digital noise of PCB.
40 Wall-Hitting Protection
Designers can use table five of motor moving to protect the wall hitting. The LONGCURV control bit has to be set to logic `1' to enable the long-curve function. The first several steps are used to decelerate the carriage moving; the other slower steps are focused on touching the home sensor. Due to the special table five, designers can replace the photo-sensor by simple, cheaper mechanical-type sensors.
