When power-on initiates the scanner, this pin is used as

mode-select pin. Normally, it is for CCD Transfer gate clock for R

channel or CIS Line start pulse.

When power-on initiates the scanner, this pin is used as

mode-select pin. Normally, it is for CCD Shift register clock2 or

CIS clock output.

When power-on initiates the scanner, this pin is used as

mode-select pin. Normally, it is for CCD Reset gate clock or

CIS clock output.

When power-on initiates the scanner, this pin is used as

mode-select pin. Normally, it is for CCD Shift register clock3.

CCD_TGX/TSTSEL0

CCD_CK2X/TSTSEL1

CCD_RSX/TSTSEL2

CCD_CK3X/TSTSEL3

Normal mode is TSTSEL[3:0] = 4’b0000

When power-on initiates the scanner, this pin is used as

motor-select pin. Normally, it is for CCD Shift register clock4, or

General Purpose Output.

When power-on initiates the scanner, this pin is used as

motor-select pin. Normally, it is for CCD Transfer gate clock of G

channel.

When power-on initiates the scanner, this pin is used as

motor-select pin. Normally, it is for CCD Transfer gate clock of B

channel.
