10.5.11 Bus Cycles in Single Address Mode
(1)
In single address mode, one byte, one word, or one longword of data is transferred at a single
transfer request and after the transfer the bus is released temporarily. One bus cycle or more by the
CPU or DTC are executed in the bus released cycles.
In figure 10.34, the TEND signal output is enabled and data is transferred in bytes from the
external 8-bit 2-state access space to the external device in single address mode (read).
