Overlay Mixing
Mode
These bits must be set to “11” in 24-bit RGB input modes. Internal mixing should not be
selected in BT.656 input mode.
00 = No mixing
01 = Internal mixing
10 = External mixing
11 = Disable overlays
11B
0
Input Resolution
This bit must be set to “0” during BT.656 input mode and when the flicker filter is enabled.
0 = Full resolution (2X upscaling disabled)
1 = SIF resolution (2X upscaling enabled)

RGB pin Assignment
select
0 = use HMP8156 assignments
1 = SCART connector compatible
0B
2
First Active
Line Select
This bit is ignored unless flicker filtering is enabled. This bit is ignored on the HMP8156.
0 = First line of active video in odd fields is on an odd line number
1 = First line of active video in odd fields is on an even line number
0B

Flicker Filter
Processing
These bits must be “00” during 8-bit YCbCr and BT.656 input modes, and SIF input resolution
mode. These bits are always “00” on the HMP8156A.
00 = No flicker filtering
01 = reserved
10 = reserved
11 = 3-line flicker filtering enabled
