23.1 Functions of Power-on-Clear Circuit
540
The power-on-clear circuit (POC) has the following functions.
• Generates internal reset signal at power on.
• Compares supply voltage (V
In the 1.59 V POC mode (option byte: POCMODE = 0), the reset signal is released when the supply voltage
(V
In the 2.7 V/1.59 V POC mode (option byte: POCMODE = 1), 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 78K0/KE2 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) or low-voltage-detector (LVI). RESF is not
cleared to 00H and the flag is set to 1 when an internal reset signal is generated by WDT or LVI.
