Functions
Sub address
bit width
STBB
This register controls the band gap VREF circuit.
0: Band gap VREF circuit enters standby mode.
1: Band gap VREF circuit enters normal operating mode.
* This must be set in line with the operation mode of ADC.

STBB_Y
STBB_B
STBB_R
These registers control the AFE standby mode (Y: STBB_Y, B: STBB_B, R: STBB_R)
0: AFE standby mode
1: AFE normal operating mode
* This must be set in line with the operation mode of ADC.

SELFCLPSTBB_Y
SELFCLPSTBB_B
SELFCLPSTBB_R
These registers control self-clamp.
(Y: SELFCLPSTBB_Y, B: SELFCLPSTBB_B, R: SELFCLPSTBB_R)
0: Self-clamp function is OFF
1: Self-clamp function is ON
*1: This is disabled when STBB_x=0 (self-clamp function is OFF).
*2: The clamp level is set to MAINCLPLVCNT_x[1:0].

MAINCLPLVCNT_Y
MAINCLPLVCNT_B
MAINCLPLVCNT_R
These registers control the clamp level.
(Y: MAINCLPLVCNT_Y, B: MAINCLPLVCNT_B, R: MAINCLPLVCNT_R)
00: 0.35V (sink tip clamp)
01: 0.50V (pedestal clamp)
10: 0.85V (center clamp)
11: Inhibited.
*: This is enabled when the self-clamp is ON.
(STBB_x=1, SELFCLPSTBB_x=1)

HPFCLPON_Y
HPFCLPON_B
HPFCLPON_R
These registers control HPF center clamp.
(Y: HPFCLPON_Y, B: HPFCLPON_B, R: HPFCLPON_R)
0: HPF center clamp is OFF
1: HPF center clamp is ON
*: This must be set OFF unless the center clamp is selected.
(MAINCLPLVCNT_x[1:0]=10).

CLPLPFON_Y
CLPLPFON_B
CLPLPFON_R
These registers control clamp LPF.
(Y: CLPLPFON_Y, B: CLPLPFON_B, R: CLPLPFON_R)
0: LPF function is OFF
1: LPF function is ON
*: This is appropriate for rejecting high-frequency noises in a weak electric field
(cut-off frequency is 1MHz).
This must be set OFF when the video signals equivalent to HD specifications is input.
