[CDS gain] Initial data: PGA[7..0] = 0, data range: 0 to 255
[The gain offset]
Initial data: GOFS[7..0] = The factory adjusted value, data range: 0 to 255

Delay time = 128 CLK x DLY[7..0] (usecond) (CLK = pixel clock)
[The clamp level] Initial data: CLAMP[7..0] = 0, data range: 0 to 31
Sets the clamp level (The clamp level of the black signal).
The gain offset (The value of the address 32H)
* GOFS[7..0]:
[The digital gain]
Initial data: DGB[7..0] = The factory adjusted value, data range: 0 to 255
Command descriptions
Sets the delay time that is from the trigger signal input to start exposure.
[The delay time for the trigger] Initial data: DLY[7..0]
＝
0, data range: 0 to 255
Sets the CDS gain (programable gain).
CDS gain = 11.1 + 0.0359 x (PGA[7..0] x 2 + GOFS[7..0]) (dB)
Analog gain = CDS gain
* CLAMP[7..0]:
The clamp level (The value of the address 38H)
(The value of the address CC & CDH)
(The value of the address CE & CFH)
* GOFS[7..0]:
* CDS_CLAMP_L[9..0]:
The gain offset (The value of the address 32H)
CDS clamp for the left side
* CDS_CLAMP_R[9..0]:
CDS clamp for the right side
[The effective lines of the variable partial scanning]
Initial data: PWR[15..0] = 2058, data range: 0 to 2058
Sets the number of the effective lines (image height) of the variable partial scanning.
Automaticaly sets 2058 when sets more then 2058.
The camera works with the full scanning when (PSR[]
＋
PWR[]) is more than 2058.
