Hello everyone for part of my college assignment I have to find some characteristics of the pic 16f84a which some of them are found in the data sheet, so far I have found the voltage levels and the reasons for such levels and the power consumption. The other features I need to find are:
Brownout Protection
Power management modes (idle,halt, wake up)
Over voltage protection (OVP)

 

Answers to all your questions are inside the 16F84A data sheet.

Read it. We all do.

I'm afraid there is no such feature as "over voltage protection".
