Single Address Mode (Write): Figure 7-29 shows a transfer example in which TEND 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.
Figure 7-30 shows a transfer example in which TEND output is enabled and word-size single address mode transfer
(write) is performed from an external device to external 8-bit, 2-state access space.
A one-byte or one-word transfer is performed for one transfer request, and after the transfer the bus is released. While the
bus is released one or more bus cycles are inserted by the CPU or DTC.
