VOP_CONFIG Bit Descriptions
Bit Name Description
63:32 RSVD (RO) Reserved (Read Only). Reads back as 0.
31:25 SPARE Spare.
24 VBI SWAP VBI Swap. When set to 1, swap upper and lower bytes of VBI data.
22:23 RSVD Reserved.
21 RGB MODE RGB Mode. Set this bit to 1 if RGB data sent: applicable in 24-bit 601 mode so as to
choose correct blanking data. If this bit is set, then blanking data is 0, otherwise it is YUV
= 10, 80, 80.
20 VALID SIG (RO) Valid Signature (Read Only). If signature enabled, this bit can be read to determine if
the signature is valid.
19 INV DE POL Invert Display Enable Polarity. Set to 1 to invert polarity of display enable (for 601
mode only).
