Programmable Registers
This register contains information about Overlay 2 indicating the size of the overlay (in
NxN blocks) and the overlay's location within the output frame buffer (in NxN blocks). In
16 pixel block size mode, only the low 7 bits of each field can be used and the most
significant bit must be set to 0.
EXAMPLE
HW_PXP_OLnSIZE_WR(2,0x10000401); // 32x8 overlay at offset +128+0
Address:
Re-
34.4.35 PXP Overlay 2 Parameters (HW_PXP_OL2PARAM)
This register contains buffer parameters for the Overlay 2 input buffer.
The S1 Overlay 2 Parameter register provides additional controls for Overlay 2.
EXAMPLE
u32 olparam;
HW_PXP_OLnPARAM_WR(2,olparam);

This field indicates the X-coordinate (in blocks) of the top-left NxN block in the overlay within the output
frame buffer.
This field indicates the Y-coordinate (in blocks) of the top-left NxN block in the overlay within the output
frame buffer.
Indicates number of horizontal NxN blocks in the image (non-rotated).
Indicates the number of vertical NxN blocks in the image (non-rotated).
