11.5.11 Bus Cycles in Single Address Mode
(1)
In single address mode, the bus is released after one byte, word, or longword has been transferred
in response to one transfer request. While the bus is released, one or more CPU, DMAC, or DTC
bus cycles are initiated.
Figure 11.34 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.
