Use the VPFE_CULLING[31-24] CULHVEN and VPFE_CULLING[23-16] CULHODD bitfields (8-bit repeating mask, one per field) to enable an optional culling operation, which culls (deletes) selected pixel data from a line. Use the VPFE_CULLING[7-0] CULV bitfield to select lines from a frame.
Table 12-1563 illustrates how the register values apply the decimation pattern to the data. The pixels in white will be saved to external memory and the shaded pixels are discarded.
