Description
Idle Cycle Insert 0
When an external read cycle and external write
cycle are performed consecutively, an idle cycle
can be inserted between the bus cycles.
0: Idle cycle not inserted
1: Idle cycle inserted
Write Data Buffer Enable
The write data buffer function can be used for
an external write cycle or DMAC single address
transfer cycle.
0: Write data buffer function not used
1: Write data buffer function used
WAIT Pin Enable
Selects enabling or disabling of wait input by
the WAIT pin.
0: Wait input by WAIT pin disabled
1: Wait input by WAIT pin enabled
Reserved
These are readable/writable bits, but the write
value should always be 0.
Idle Cycle Insert 2
When an external write cycle and external read
cycle are performed consecutively, an idle cycle
can be inserted between the bus cycles.
0: Idle cycle not inserted
1: Idle cycle inserted
Note: Bit 2 is a reserved bit in the H8S/2678
Reserved
These bits can be read from or written to.
However, the write value should always be 0.
WAIT pin can be used as I/O port
