Bus control with memory expansion
The 3806 group has a built-in ONW function to facilitate access to
external memory and I/O devices in memory expansion mode or
microprocessor mode.
If an “L” level signal is input to the ONW pin when the CPU is in a
read or write state, the corresponding read or write cycle is ex-
tended by one cycle of . During this extended period, the RD or
___
WR signal remains at “L”. This extension period is valid only for
writing to and reading from addresses 0000
0440
memory expansion mode, and only read and write cycles are ex-
tended.

:
Period during which ONW input signal is received
During this period, the ONW signal must be fixed at either “H” or “L”. At all other times, the input level of the ONW
signal has no affect on operations.
The bus cycles is not extended for an address in the area 0008
