Chaps, can someone tell me if the LVP / RB5 pin on a PIC18F452 needs to be tied low? - my design uses high voltage programming, never uses LVP. Some folk talk about needing to tie LVP low, but reading the datasheet, I cannot see why. If I do tie RB5 low, then I lose a pushbutton, since I have a bank of 4 switches on RB4,5,6,7 which use the internal weak pull-ups, with the switches pulling low through 1k when pressed.
