R/W
0
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.
Offset 0x10 E210

Layer N Pitch B
R/W
0
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.

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.

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. This Register holds the source address for the UV plane in
semi planar modes.

Line Increment Packed
R/W
0xFFFFh This register determines whether a layer line is repeatedly fetched
from memory or not.
Round Down(216/(Line Increment Packed))= #of times the same
line is fetched i.e., 0x8000H would fetch each line exactly twice (line
doubling).
Offset 0x10 E224

R/W
0xFFFFh This register determines whether a layer line is repeatedly fetched
from memory or not.
Round Down(216/(Line Increment Semi Planar))= #of times the
same line is fetched i.e., 0x8000H would fetch each line exactly
twice (line doubling).
Offset 0x10 E228
