Figure 6-2: BLTxPTR and BLTxMOD calculations
NOTE
The blitter can be used to process linear rather than rectangular regions by setting the
horizontal or vertical count in BLTSIZE to 1.
Because each DMA channel has its own modulo register, data can be moved among
bitplanes of different widths. This is most useful when moving small images into larger
screen bitplanes.
