Like many PIC's, the 16F914 that I am using can implement the mclr/vpp pin to be a digital input as well.
   
  Typically I'd shy away from using it, but im forced as I need ONE more input...
   
  So, programming it in the config word is easy, and I assume that defining it as the alternate mode, that MCLR works in conjunction with the powerup timer to reset the device on power up.
   
  But what about the ICD....does it but 12V on this pin during programming still? I assume it does as the ICD doesnt know anything about that.  
   
  So, I believe I need to isolate the digital input connection from the VPP signal of the ICD during programming to protect the chip that is driving it.  Comments?
