360 AMD Geode™ SC1200/SC1201 Processor Data Book
Video Processor Module - Video Processor Registers - Function 4
32579B
10 Auto-Flip. Video port operation mode.
0: The video port automatically detects the even and odd fields based on the VP_HREF and VP_VSYNC_IN signals or the
CCIR-656 control codes.
1: The even/odd field detect logic is disabled and the video port automatically toggles between the even and odd buffers
during capture. The odd buffer is the first to be filled in this mode.
This bit must be programmed to 0 when Direct Video mode is used. Direct Video mode is used when VID_SEL = 10
(F4BAR0+Memory Offset 400h[1:0]). Otherwise the video select from the GX1 module. VID_SEL indicates the source of the
video data.)
9 Capture (Store to Memory) VBI Data.
0: Disable.
1: Enable.
8 Capture (Store to Memory) Video Data.

1: Odd field is being processed.
23:22 Reserved. (Read Only)
21 Base Register Not Updated. (Read Only) When set to 1, this bit indicates that one of the base registers (at
F4BAR2+Memory Offset 20h, 24h, 40h, and 44h) has been written but has not yet been updated.
0: All base registers are updated.
1: One or more of the base registers has not been updated.
20 FIFO Overflow Status Indication.
0: No overflow occurred.
1: An overflow occurred for the FIFO between the VIP and the Fast X-Bus.
Writing a 1 to this bit clears the status.
