WebJul 12, 2024 · \$\begingroup\$ For example, BOR operates at typical 4.0V with a range of 3.7 to 4.35. The MCU requires 4.0 to 5.5 V to be guaranteed to operate properly. So there is a 300mV range from 3.7 to 4.0V where behavior is undefined- it might spin motors, run heaters out of control, or trash non-volatile memory locations, for example. WebPOR. Power On Reset starts PIC microcontroller initialization when it detects a rising edge on MCLR. PWRT. If you enable this then 72ms after a POR the PIC microcontroller is started. OST.
