7. DMA Controller
If M (1 to 255) is the size of the block transferred at each request and N (1 to 65,536) is the
number of blocks to be transferred, then ETCRAH and ETCRAL should initially be set to M and
ETCRB should initially be set to N.
Figure 7.10 illustrates how block transfer mode operates. In this figure, bit TMS is cleared to 0,
meaning the block area is the destination.
