AMIS-720658: Contact Image Sensor
Data Sheet
Figures 9 and 10 show the timing of the SI/SO, which comes out in line with the 334^th pixel for the 600dpi mode and the 162^nd pixel for
the 300dpi mode. The SO from the first sensor enters as the SI clock of the second and subsequent sensors, hence all subsequent
sensors will start their register scan after each of the preceding sensors completes its scan.
The last active pixel of each sensor is the 344^th pixel for the 600dpi mode and 172^nd pixel for the 300dpi mode.
