Programmable Registers
34.4.36 PXP Overlay 2 Parameters 2 (HW_PXP_OL2PARAM2)
This register contains buffer parameters for the Overlay 2 input buffer.
The Overlay 2 Parameter 2 register is reserved for future use.
Address:
Re-
34.4.37 PXP Overlay 3 Buffer Pointer (HW_PXP_OL3)
Overlay 3 Buffer Address Pointer. This register points to the beginning of the RGB Overlay
3 input buffer.
This register points to the is used by the logic to point to the current output location for the
RGB frame buffer.

HW_PXP_OL2PARAM field descriptions (continued)
Embedded — Indicates that the OL pixel alpha value will be used to blend the OL with S0.The ALPHA
field is ignored.
Override — Indicates that the value in the ALPHA field should be used instead of the alpha values
present in the input pixels.
Multiply — Indicates that the value in the ALPHA field should be used to scale all pixel alpha values.
Each pixel alpha is multiplied by the value in the ALPHA field.
ROPs — Enable ROPs. The ROP field indicates an operation to be performed on the overlay and S0
pixels.
