7.5.5
Single address mode can only be specified for channel B. This mode can be specified by setting
the SAE bit in DMABCR to 1 in short address mode.
One address is specified by MAR, and the other is set automatically to the data transfer
acknowledge pin (DACK). The transfer direction can be specified by the DTDIR bit in DMACR.
Table 7.9 summarizes register functions in single address mode.

MAR:
IOAR: I/O address register
ETCR: Execute transfer register
DTDIR: Data transfer direction bit
DACK: Data transfer acknowledge
Note: * See the operation descriptions in sections 7.5.2, Sequential Mode, 7.5.3, Idle Mode, and
MAR specifies the start address of the transfer source or transfer destination as 24 bits.
IOAR is invalid; in its place the strobe for external devices (DACK) is output.
