Notes 1. Only the contents of the PC among hardware become undefined during reset input and oscillation
2. If the reset signal is input in the standby mode, the status before reset is retained even after reset.
3. Set the following value before operating each device even though the initial value is CFH.
4. Set the following value before operating each device even though the initial value is 0CH.
5. Bit 2 changes according to V
stabilization time wait. The other statuses do not differ from those after reset.
