Description
Standby modes. 0: normal operation; 1: Standby1 mode;
2: Standby2 mode; 3: Standby3 mode.
0: disable OB clamp; 1: enable OB clamp.
0: select normal OB clamp settling; 1: select fast OB clamp settling.
0: ignore CDS gain; 1: very fast clamping when CDS gain is updated.
0: blank data outputs to 0 during PBLK;
1: blank data outputs to programmed clamp level during PBLK.
0: enable input dc restore circuit during PBLK;
1: disable input dc restore circuit during PBLK.
0: data outputs are driven; 1: data outputs are three-stated.
0: latch data outputs using the rising edge of DOUTPHASEP
(DOUTPHASEP register setting);
1: output latch is transparent.
1: enable gray encoding of the digital data outputs.
Set to 0.
Do not access, or set to 0.
Do not access, or set to 0xFFFFFF.
CDS gain setting. 0: 3 dB; 4: 0 dB; 6: +3 dB; 7: +6 dB.
All other values are invalid.
VGA gain, 6 dB to 42 dB (0.035 dB per step).
Optical black clamp level, 0 to 1023 LSB (1 LSB per step).
0: no division of CLI; 1: divide CLI input frequency by 2.

Description
Software reset. Bit self-clears to 0 when a reset occurs.
1: reset Address 0x00 to Address 0xFF to default values.
0: make all outputs dc inactive; 1: enable outputs at next VD
edge.
1: configure SYNC pin as RSTB input signal.
Test mode only. Must be set to 0.
1: external synchronization enable (configures Pin D3 as an
input).
SYNC active polarity.
Suspend clocks during SYNC active pulse. 0: don’t suspend;
1: suspend.
1: enable enhanced sync/shutter operations.
1: mask HD during SYNCSUSPEND.
1: mask VD during SYNCSUSPEND.
1: mask XV outputs during SYNCSUSPEND.
1: enable use of shadow registers.
Test mode only. Must be set to 0.
1: writes to shadow bits affect shadow registers, not primary.
1: initiate software SYNC event (self-clears to 0 after SYNC).
Timing core reset bar. 0: reset TG core; 1: resume operation.
