8.4.1
The transfer modes of the EXDMAC are summarized in table 8.2.
Table 8.2
The transfer mode can be set independently for each channel.
In normal transfer mode, a one-byte or one-word transfer is executed in response to one transfer
request. With auto requests, burst or cycle steal transfer mode can be set. In burst transfer mode,
continuous, high-speed transfer can be performed until the specified number of transfers have
been executed or the transfer enable bit is cleared to 0.
