Section 8 EXDMA Controller (EXDMAC)
8.4
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.
