7.13 Power-on-Clear (POC) Circuit
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 if the supply voltage (V
Caution If the low-voltage detector (LVI) is set to ON by an option byte by default, the reset signal is
