CIS TR1 Timing Mode

0 0 Off - use standard CCD Timing

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.

11N/A

SENSOR PIXEL CONFIGURATION

Optical Black Pixels Start

nnn nnnnnn pixels (0 - 255)

Optical Black Pixels End

nnn nnnnnn pixels (0 - 255)

Active Pixels Start - MSB

n nnnnn

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)

Active Pixels Start - LSB

nnn nnnnn

Line End - MSB

n nnnnn

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.

Line End - LSB

nnn nnnnn

PIXEL DATA RANGE TO PROCESS

Data Pixels Start - MSB

n nnnnnn pixels (Active Pixels Start - 16383)

This selects the start of the range of pixels transmitted

to the PC. This value must be >= Active Pixels Start

Data Pixels Start - LSB

nnn nnnnn

Data Pixels End - MSB

n nnnnnn pixels (Data Pixels Start - [Line End - 20])

This selects the end of the range of pixels transmitted

to the PC. This value must be <= [Line End - 20]

Data Pixels End - LSB

nnn nnnnn
