Programmable Registers
EXAMPLE
u32* overlay_ptr;
HW_PXP_OLn_WR(1,overlay_ptr);
Address:
Re-
34.4.30 PXP Overlay 1 Size (HW_PXP_OL1SIZE)
This register contains buffer size/location information for the Overlay 1 input buffer.
This register contains information about Overlay 1 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(1,0x10000401); // 32x8 overlay at offset +128+0
