Single address mode can only be specified for channel B. This mode can be specified by setting
the SAE bit in DMABCRH 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 7.8 summarizes register functions in single address mode.
Table 7.8
Register
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.
Figure 7.9 illustrates operation in single address mode (when sequential mode is specified).
