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 bus cycles are initiated.
Figure 7.29 shows an example of transfer when TEND output is enabled, and longword-size,
single address mode transfer (write) is performed from an external device to external 16-bit, 2-
state access space.
