AMD SC3200 Capture Store to Memory VBI Data, Capture Store to Memory Video Data, 2322, 1918, 346

32581C Video Processor Module - Video Processor Registers - Function 4

Table 7-8. F4BAR2+Memory Offset: VIP Configuration Registers (Continued)

Bit Description

10Auto-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 CCIR656 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.)

9Capture (Store to Memory) VBI Data.

0:Disable.

1:Enable.

8Capture (Store to Memory) Video Data.

0:Disable.

1:Enable.

7:2	Reserved. Must be set to 0.
1:0	Run Mode Capture. Selects capture run mode.
	00: Stop capture at end of current line.
	01: Stop capture at end of current field.
	10	Reserved.
	11: Start capture at beginning of next field.
Offset 08h-0Bh		Video Interface Status Register (R/W)	Reset Value: xxxxxxxxh
31:25	Reserved. (Read Only)

24Current Field. (Read Only)

0:Even field is being processed.

1:Odd field is being processed.

23:22 Reserved. (Read Only)

21Base 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.

20FIFO 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.

19:18 Reserved. (Read Only)

17Line Interrupt (INTC#) Pending Status.

0:Interrupt not pending.

1:Interrupt pending.

Writing a 1 to this bit clears the status.

16Field Interrupt (INTC) Pending Status.

0:Interrupt not pending.

1:Interrupt pending.

Writing a 1 to this bit clears the status.

15:10 Reserved. (Read Only)

9VBI Data Capture Active. (Read Only)

0:VBI data is not being stored to memory.

1:VBI data is now being stored to memory.
