25 16 GPIO Ports
You can set input or output for each GPIO pin of the GPIO1~16 separately.
Such as keypads inputs, document sensor for sheet-fed or motor power control…etc.
Note : there are two pins for special function. One is GPIO12 and the other is GPIO11.
GPIO12: 1. Pull up by resister to indicate that ASIC turn on lamp power whenever power on initial.
2. Pull down by resister to indicate that ASIC turn off lamp power whenever power on initial.
3. This pin can control bi-polar motor driver 2916,6219,3966 or 3955 Vref in order to control
Imax. current.
GPIO11: This pin can control bi-polar motor driver 2916,6219,3966 or 3955 Vref in order to control
Imax. current.
26 GPO17~18 Ports or Motor MTR_PH6~7 Two Phase
You can select 2 pins for 3955 2 phase MTR_PH6~7 output or GPO17~18 output.
27 GPO13 Port or Motor Trigger Signal for ADF
Motor trigger signal for ADF motor moving. It can be controlled under scanning condition.
28 Power on Check
The default status of the PWRBIT is reset. You can set the PWRBIT and then read back the status in order to
check the power status. This operation is able to check first time power on or not.
29 RAM Test
S/W can test DRAM/SRAM IC by writing and reading back for checking.
30 LED Blinking
Support LED-blinking function. It is implemented in GPIO13~18 pins.
31 Support Back Scanning
Support forward or backward scanning type.
