Programmable Registers
Address:
Re-
34.4.25 PXP Overlay 0 Buffer Pointer (HW_PXP_OL0)
Overlay 0 Buffer Address Pointer. This register points to the beginning of the RGB Overlay
0 input buffer.
This register points to the is used by the logic to point to the current output location for the
RGB frame buffer.
