I have to buy a new PIC16F1829 chip and test it ,will release the result here , but the think is really unusual for me is that why with this kind of damage my PIC chip is working totally fine!!!
Why do you think anything is wrong with it? - program it to do something, and configure unused I/O pins as outputs.
I've just measured an 18F27K42 I'm playing with, and reading an analogue input and outputting variable PWM it's drawing 16mA running at 64MHz.
