Description
Layer N Source Data Start Address B in bytes. This sets starting
address B for data transfers from the linear Frame Buffer memory to
Layer N. For semi planar and planar modes this address points to
the Y plane.
Note: It should be aligned on a 128-byte boundary. It has to be
8-byte aligned.
Layer N Source Data Pitch B in bytes sets pitch B for data transfers
from the linear Frame Buffer memory to Layer N. For semi planar
and planar modes this determines the pitch for the Y plane.
The value has to be rounded up to the next 64-bit word.
Number of dummy pixels to be inserted between layer video lines
Layer N Source Data Start Address A in bytes. This sets starting
address A for data transfers from the linear Frame Buffer memory to
Layer N. This Register holds the source address for the UV plane in
semi planar modes.
Note: It should be aligned on a 128-byte boundary. It has to be
8-byte aligned.
