When power-on initiates the scanner, this pin is used as
mode-select pin. Normally, it is for CCD Shift register clock3.
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.
