LIM16

[REV_ID=0 TW2864] This function doesn’t exist.This bit is always 0.

[REV_ID>=1 TW2864]

Output ranges are limited to 2~254(default)

Output ranges are limited to 16~235 for Y and 16~239 for CbCr

PBREFEN

[REV_ID=0 TW2864] This function doesn’t exist.This bit is always 0.

[REV_ID>=1 TW2864] Audio ACKG Reference(refin) input select

ACKG has video VRST refin input selected by VRSTSEL register

ACKG has audio ASYNP refin input.(default)

YCBCR422

Control YCbCr 4:2:2 output mode

Normal 4:2:2 output mode (default)

Averaging 4:2:2 output mode

HA656MD

Control HACTIVE signal output on H-Down Scaling output mode.

HACTIVE signal is always HACTIVE register’s length

(REV_ID=0 TW2864 default)

HACTIVE signal is same as DVALID signal in H-Down Scaled video output(TW2834 need 1).

(REV_ID>=1 TW2864 default)

VBI_FRAM

Test purpose only. 0 default

CNTL656

Select invalid data value.

0x80 and 0x10 code will be output as invalid data during active video line(default)

0x00 code will be output as invalid data during active video line.

VSCL_SYNC

Enable the optional ITU-R.656 sync code format.

Skip ITU-R BT.656 sync code for non-valid vertical line (default)

Standard ITU-R BT.656 sync code on any vertical line.

HA_EN

Control HACTIVE output during vertical blanking period.

HACTIVE output is disabled during vertical blanking period

HACTIVE output is enabled during vertical blanking period (default)
