After one byte or word has been transferred in response to one transfer request, the bus is released.
While the bus is released, one or more CPU, DMAC, or DTC bus cycles are initiated.

Figure 8.24 shows an example of transfer when ETEND output is enabled, and byte-size, single
address mode transfer (write) is performed from an external device to external 8-bit, 2-state access
space.
