Total line length in pixels including blanking. Also the ending value for the Frame Pixel
Counter. Lines always begin with a horizontal blanking interval, and the image starts after
the blanking interval and runs to the end of the line.
Pixel number in Frame Pixel Counter of starting pixel of active video area within the line.
Note: Must be even.
Video Image height in lines.
Video Image line (scaled) output width in pixels. Must be even for upscaling by 2×.
Threshold image line number in the Image Line Counter for the YTR interrupt.
Can be reprogrammed on a frame-by-frame basis.
Image vertical offset in lines from the top of the active video window.
Image horizontal offset in pixels from the start of the active video window.
Starting image line of YUV overlay within the image.
Zero indicates that the overlay starts at the same line as the image.
Starting image pixel of the YUV overlay within the image. ‘0’ indicates that the overlay
starts at same pixel as the image. Note: Must be even.
Alpha blend value used for YUV 4:2:2+alpha format overlays when the alpha bit = 1.
Height of the YUV overlay image in lines. Note: The height of the overlay should be cho-
sen such that it does not extend beyond the image area.
Width of the YUV overlay image in pixels. Note: Must be even.
Alpha blend value used for YUV 4:2:2+alpha format overlays when the alpha bit = 0.
Y-component buffer address or Buffer 1 address.
• In video-refresh modes: Y-component starting byte address.
• In data-streaming and message-passing modes: Buffer 1 starting byte address. Note:
U-component buffer address or Buffer 2 address.
• In video-refresh modes: U-component starting byte address
• In data-streaming mode: Buffer 2 starting byte address; must be 64-byte aligned
• Not used in message-passing mode
V-component buffer address or Buffer 1 length.
• In video-refresh modes: V-component starting byte address
• In data-streaming and message-passing modes: Buffer 1 length in bytes. Note: must be
Overlay-image buffer address or Buffer 2 length.
