Section 6 Bus Controller
Figure 6.14 shows an 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.
