14.5.3 Timing Relationships
Figure 14-2 shows the timing relationships in the hardware standby mode.
In the sequence shown, first RES goes Low, then STBY goes Low, at which point the H8/330
enters the hardware standby mode. To recover, first STBY goes High, then after the clock settling
time, RES goes High.
