Bit	Description

Offset 90h-93h		Video Request Register (R/W)	Reset Value: 001B0017h

31:28	Reserved. Set to 0.

27:16	VIDEO_X_REQ (Video Horizontal Request). Determines the horizontal (pixel) location at which to start requesting video
	data out of the video FIFO. This value is calculated according to the following formula:
	Value = Desired screen position + (H_TOTAL – H_SYNC_END) – 2.

15:11	Reserved

10:0	VIDEO_Y_REQ (Video Vertical Request). Determines the line number at which to start requesting video data out of the
	video FIFO. This value is calculated according to the following formula:
	Value = Desired screen position + (V_TOTAL – V_SYNC_END) + 1.

Offset 94h-97h		Alpha Watch Register (RO)	Reset Value: 00000000h

Alpha values may be automatically incremented/decremented for successive frames. This register can be used to read the alpha values that are being used in the current frame.

31:24	Reserved.

23:16	ALPHA3_VAL (Value for Alpha Window 3).

15:8	ALPHA2_VAL (Value for Alpha Window 2).

7:0	ALPHA1_VAL (Value for Alpha Window 1).

Offset 98h-3FFh		Reserved

Offset 400h-403h		Video Processor Display Mode Register (R/W)	Reset Value: 00000000h
Selects various Video Processor modes.

31	Video FIFO Underflow (Empty).
	0: No underflow has occurred.
	1: Underflow has occurred.
	Write 1 to reset this bit.

30	Video FIFO OverFlow (Full).
	0: No overflow has occurred.
	1: Overflow has occurred.
	Write 1 to reset this bit.

29	Reserved. Write as read.

28	Reserved. Write as read.

27:4	Reserved. Set to 0.

3	Reserved. Write as read.

2	Note:	Reserved. Write as read.

1:0	VID_SEL (Video Select). Selects the source of the video data.
	00: GX1 module.
	10: VIP block.
	01: Reserved.
	11: Reserved.
	The GX1 module’s video clock must be active at all times, regardless of the source of video input.

Offset 404h-407h		Reserved	Reset Value: 00000000h

Offset 408h-40Bh		Video Processor Test Mode Register (R/W)	Reset Value: 00000000h
