During reset input or oscillation stabilization time wait, only the PC contents among the hardware statuses
become undefined. All other hardware statuses remain unchanged after reset.
When a reset is executed in the standby mode, the pre-reset status is held even after reset.
16-bit timer/event counter 01 is available only for the
and 78F0138.
8-bit timer H1 only.
