Note 1 You must write 1 to bit4.
2. When the supply voltage rises, the reset state must be maintained by the voltage detection circuit or external reset
before the supply voltage reaches the working voltage range shown in the AC characteristics of the data sheet;
When the supply voltage drops, it must be reset through sleep mode transfer, voltage detection circuitry, or
external reset before the supply voltage drops below the operating voltage range.
The operating voltage range depends on the setting of the user option byte (000C2H).
