Figure 8.18 illustrates operation in block transfer mode when transfer source is designated as a
block area.
ETCRAL is decremented by 1 each time a byte or word transfer is performed. In response to a
single transfer request, burst transfer is performed until the value in ETCRAL reaches H'00.
ETCRAL is then loaded with the value in ETCRAH. At this time, the value in SAR or DAR for
which a block designation has been given by the BLKDIR bit in DMACRF is restored in
accordance with the DTSZ, SAID/DAID, and SAIDE/DAIDE bits in DMACRS.
