Figure 6-14 Example of Wait State Insertion Timing
The settings after a power-on reset are: 3-state access, 3 program wait state insertion, and WAIT input disabled. When a
manual reset* is performed, the contents of bus controller registers are retained, and the wait control settings remain the
same as before the reset.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.
