23.1 Functions of Power-on-Clear Circuit
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
The power-on-clear circuit (POC) is mounted onto all 78K0R/Lx3 microcontroller products.
The power-on-clear circuit 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
