Description
Output format dither mode
Output format alpha mode
Output formats
Line size
Used for horizontal cropping after scaling.
Remark: Internal buffer lines are only 1024 pixels. Horizontal
and vertical scaling need to be ordered such that the
intermediate result fits into 1024 pixels buffer lines.
Line count
Used for vertical cropping after scaling.
Base address DMA #1
Used depending on PSU_BAMODE setting.
Base address byte offset DMA #1
Bits define pixel offset within multi pixel 64-bit words (e.g., a 16-bit
pixel can be placed on any 16-bit boundary).
00: no dithering
01: error dispersion (never reset pattern)
10: error dispersion (reset pattern at startup)
11: error dispersion (reset pattern every field)
00: no alpha (alpha byte not written to memory)
01: alpha byte written (see Color Keying Control)
