13.1 Functions of Power-on-Clear Circuit
204
The power-on-clear circuit (POC) has the following functions.
Cautions 1. If an internal reset signal is generated in the POC circuit, the reset control flag register

indicates the reset cause is located in the reset control flag register (RESF) for when an internal reset
signal is generated by the watchdog timer (WDT) or low-voltage-detection (LVI) circuit. RESF is not
cleared to 00H and the flag is set to 1 when an internal reset signal is generated by WDT or LVI.
For details of RESF, see CHAPTER 12 RESET FUNCTION.
