CIS TR1 Timing Mode 1:
TR1 pulse = exactly one Ø clock,
starting at rising edge of Ø1
CIS TR1 Timing Mode 2:
TR1 pulse = exactly one Ø clock,
TR1 centered around Ø1 high.
Off: Normal operation
On: RS pulse held high during entire Optical Black
period
n pixels (10 - 16383)
This is where image data starts coming out of the
sensor, and determines the pixel where offset and
shading correction begins (pixel 0 in the DataPort)
n pixels (0 - 16383)
This selects the pixel count at which the current line is
ended and the next line begins. This determines the
integration time of one line.
This selects the start of the range of pixels transmitted
to the PC. This value must be >= Active Pixels Start
This selects the end of the range of pixels transmitted
to the PC. This value must be <= [Line End - 20]
