This 8-bit register specifies the last two digits of the product number. It is a read-only register.
Data written to it is ignored.
000 = (M) NTSC
001 = (M) NTSC with a 0 IRE setup; also called (NSM) NTSC
010 = (B, D, G, H, I) PAL
011 = (M) PAL
100 = (N) PAL
101 = combination (N) PAL; also called (CN) PAL
110 = reserved
111 = reserved
00 = Composite + Y/C
01 = reserved
10 = Composite + RGB (no sync on green)
11 = Composite + RGB (with sync on green)
000 = 16-bit 4:2:2 YCbCr
001 = 8-bit 4:2:2 YCbCr
010 = 8-bit BT.656
011 = 16-bit linear RGB
100 = 16-bit gamma-corrected RGB
101 = 24-bit linear RGB
110 = 24-bit gamma-corrected RGB
111 = Blue screen
These bits are ignored except during linear RGB input modes.
0 = 1 / 2.2
1 = 1 / 2.8
These bits must be set to “11” in 24-bit RGB input modes. Internal mixing should not be se-
lected in BT.656 input mode.
00 = No mixing
01 = Internal mixing
10 = External mixing
11 = Disable overlays
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)
