Section 8 EXDMA Controller (EXDMAC)
8.4.10
Single Address Mode (Read): Figure 8.22 shows an example of transfer when ETEND output is
enabled, and byte-size, single address mode transfer (read) is performed from external 8-bit, 2-
state access space to an external device.
Figure 8.23 shows an example of transfer when ETEND output is enabled, and word-size, single
address mode transfer (read) is performed from external 8-bit, 2-state access space to an external
device.
