Section 7 DMA Controller (DMAC)
7.5.2
Sequential mode can be specified by clearing the RPE bit in DMACR to 0. In sequential mode,
MAR is updated after each byte or word transfer in response to a single transfer request, and this is
executed the number of times specified in ETCR. One address is specified by MAR, and the other
by IOAR. The transfer direction can be specified by the DTDIR bit in DMACR.
Table 7.5 summarizes register functions in sequential mode.
Table 7.5
Register
MAR specifies the start address of the transfer source or transfer destination as 24 bits. MAR is
incremented or decremented by 1 or 2 each time a byte or word is transferred. IOAR specifies the
lower 16 bits of the other address. The 8 bits above IOAR have a value of H'FF.
Figure 7.3 illustrates operation in sequential mode.
