Wait Control
When accessing external space, the H8S/2357 Group can extend the bus cycle by inserting one or more wait states (T
).
w
There are two ways of inserting wait states: program wait insertion and pin wait insertion using the WAIT pin.
Program Wait Insertion: From 0 to 3 wait states can be inserted automatically between the T
state and T
state on an

individual area basis in 3-state access space, according to the settings of WCRH and WCRL.
Pin Wait Insertion: Setting the WAITE bit in BCRL to 1 enables wait insertion by means of the WAIT pin. Program wait
insertion is first carried out according to the settings in WCRH and WCRL. Then , if the WAIT pin is low at the falling
state is inserted. If the WAIT pin is held low, T
edge of ø in the last T
or T
state, a T
states are inserted until it goes

high.
This is useful when inserting four or more T
states, or when changing the number of T
states for different external

devices.
The WAITE bit setting applies to all areas.
