19.1 Functions of Power-on-Clear Circuit
624
The power-on-clear circuit (POC) has the following functions.
• Generates internal reset signal at power on.
• Compares supply voltage (V
The reset signal is released when the supply voltage (V
Caution If an internal reset signal is generated in the POC circuit, the reset control flag register (RESF)
Remark This product incorporates multiple hardware functions that generate an internal reset signal. A flag

that indicates the reset source is located in the reset control flag register (RESF) for when an internal
reset signal is generated by the watchdog timer (WDT), low-voltage detector (LVI), or illegal
instruction execution. RESF is not cleared to 00H and the flag is set to 1 when an internal reset
signal is generated by WDT, LVI or illegal instruction execution. For details of RESF, see CHAPTER
