23.1 Functions of Power-on-Clear Circuit
The power-on-clear circuit (POC) has the following functions.
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)
