Figure 7.27 shows a transfer example in which TEND 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.
A byte or word transfer is performed for a single transfer request, and after the transfer, the bus is
released. While the bus is released, one or more bus cycles are executed by the CPU or DTC.
In the transfer end cycle (the cycle in which the transfer counter reaches 0), a one-state DMA dead
cycle is inserted after the DMA write cycle.
