Field_ID
R
-
Field_ID is reset by disabling the screen timing generator
Field_ID is incremented with each rising edge of VSYNC and wraps
around after reaching the value 0x7 which yields a sequence of 8
elds which could be differentiated by using the Field_ID register.

Layer & Mixer Registers
The structure of each layer function block is identical. The register for a function such as Source Address in Layer 1, has the
same structure as the corresponding register in Layer 2. Layer one starts at offset 0x200 from the QVCP base address.
Layer two starts at offset 0x400 from the QVCP base address.
Offset 0x10 E200

Layer N Source Address
A
R/W
0
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. For semi planar and planar modes this address points to
the Y plane.
Note: It should be aligned on a 128-byte boundary for memory
performance reasons. It has to be 8-byte aligned.
Offset 0x10 E204
Layer Source Pitch A (Packed/Semi Planar Y)

22:0
Layer N Pitch A
R/W
0
Layer N Source Data Pitch B in bytes. This sets pitch A 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.
Offset 0x10 E208
Layer Source Width (Packed/Semi Planar Y)
31:23
Unused
-
12:0
Layer N Source Width
R/W
0
Layer N source width in bytes. For semi planar and planar modes
this determines the source data with in bytes for the Y plane. The
value has to be rounded up to the next 64-bit word.
Offset 0x10 E20C
