Description
Offset component #4 (alpha or V)
Index of MSB position within 32 bit word (0-31)
Size component #3 (V or B or Y2)
number of bits minus 1 (e.g. 7 = 8 bits per component)
Offset component #3 (V or B or Y2)
index of MSB position within 32 bit word (0-31)
Size component #2 (U or G)
number of bits minus 1 (e.g. 7 = 8 bits per component)
Offset component #2 (U or G)
index of MSB position within 32 bit word (0-31)
Size component #1 (Y or R)
number of bits minus 1 (e.g. 7 = 8 bits per component)
Offset component #1 (Y or R)
index of MSB position within 32 bit word (0-31)
Base address DMA #1
used depending on PFU_BAMODE setting
Base address byte offset DMA #1
bits define pixel offset within multi pixel 64 bit words
(e.g. a 16bit pixel can be placed on any 16 bit boundary)
Line pitch DMA #1, signed value (two’s complement)
Used for all packed formats and for plane 1.
Base address DMA #2
Used depending on PFU_BAMODE setting.
Base address byte offset DMA #2
Bits define pixel offset within multi pixel 64-bit words (e.g., a 16-bit
pixel can be placed on any 16-bit boundary).
Line pitch DMA #2, signed value (two’s complement)
Used for planes 2 and 3.
Base address DMA #3
Used depending on PFU_BAMODE setting.
