Notes 1. During reset input or oscillation stabilization time wait, only the PC contents among the hardware
2. When a reset is executed in the standby mode, the pre-reset status is held even after reset.
3. Although the initial value is CFH, set the following value for each version.
4. Although the default value of this register is 0CH, initialize this register to 0AH.
statuses become undefined. All other hardware statuses remain unchanged after reset.
