Section 7 Bus Controller
7.6.4
When accessing external space, this LSI can extend the bus cycle by inserting one or more wait
states (Tw). There are two ways of inserting wait states: program wait insertion and pin wait
insertion using the WAIT pin.
(1) Program Wait Insertion

From 0 to 3 wait states can be inserted automatically between the T
individual area basis in 3-state access space, according to the settings of WCRH and WCRL.
