7.5.6
In normal mode, transfer is performed with channels A and B used in combination. Normal mode
can be specified by setting the FAE bit in DMABCR to 1 and clearing the BLKE bit in DMACRA
to 0.
In normal 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 ETCRA. The transfer source is
specified by MARA, and the transfer destination by MARB.
Table 7.10 summarizes register functions in normal mode.
Table 7.10 Register Functions in Normal Mode

Legend:
MARA: Memory address register A
MARB: Memory address register B
ETCRA: Execute transfer count register A
MARA and MARB specify the start addresses of the transfer source and transfer destination,
respectively, as 24 bits. MAR can be incremented or decremented by 1 or 2 each time a byte or
word is transferred, or can be fixed.
Incrementing, decrementing, or holding a fixed value can be set separately for MARA and
MARB.
The number of transfers is specified by ETCRA as 16 bits. ETCRA is decremented each time a
transfer is performed, and when its value reaches H'0000 the DTE bit is cleared and transfer ends.
If the DTIE bit is set to 1 at this time, an interrupt request is sent to the CPU or DTC.
The maximum number of transfers, when H'0000 is set in ETCRA, is 65,536.
