I read before that keeping this port in high state prevents accidental resets to the micro-controller because when this pin is at 0v the microcontroller resets
and so keeping it in high state prevents reseting
But according to this link **broken link removed**
VPP reset at low state
but at high state it starts at 1st line everytime !
isn't starting at first line is the meaning of reseting ??
Both statements say the same... A reset occurs when MCLR is pulled low... The PIC runs when its kept high.
VPP is the 12+ volts required for programming.
Actually the pic resets at the highest address then rolls to 0... Most of the locations at power up are all set. So the PC on a pic14 will be at b'1111 1111 1111'
Then it rolls over to 0 where the reset vector is...
