24.1 Functions of Power-on-Clear Circuit
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
The power-on-clear circuit (POC) is mounted onto all 78K0/Kx2 microcontroller products.
The power-on-clear circuit 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
exceeds 1.59 V ±0.15 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) is

cleared to 00H.
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.
For details of RESF, see CHAPTER 23 RESET FUNCTION.
