Hello,
i'm new to embedded systems and i started to self-learn PIC micro controllers
and i have a question :
Pin 1 from pic 16877A called MCLR/VPP as shown in the following picture
http://t0.gstatic.com/images?q=tbn:ANd9GcS49J_O__Kz2dKG71Y-FduzPUHJBgybBjawV-O6DxbELiZsUi2A
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 ??
