4 GPU Register Set
Graphic Processing Unit
4.1 Description
Addresses are hexadecimal byte addresses in MCU address space, initial values are given as mnemonic or
hexadecimal, as appropriate. Bit slices are according to the word starting at address Addr. Registers marked
in Lock are read-only during DIR_MTimingOn set to 1.

103C
Layer 0 to Layer 15 physical address in VideoRAM
(These are actually SDC registers, included here for
completeness of layer description records only.)
LDR0_DomSz …
LDR15_DomSz

107C
Layer 0 to Layer 15 domain size, i.e. size of whole
area covered by the layer
[29:16] = DX = width (unsigned integer)
(These are actually SDC registers, included here for
completeness of layer description records only.
There is no DY stored, it is the user’s responsibility
to provide sufficient RAM space for each layer.)
