Section 11 EXDMA Controller (EXDMAC)
(2)
In burst mode, one-byte, one-word, or one-longword transfer is executed continuously until the
transfer end condition is satisfied.
Once burst transfer starts, requests from other channels, even of higher priority, are held pending
until burst transfer ends.
Figure 11.27 shows an example of transfer when ETEND output is enabled, and word-size, normal
transfer mode (burst mode) is performed from external 16-bit, 2-state access space to external 16-
bit, 2-state access space.
