Hi All,

All the PIC documentation I have ever read says to tie the MCLR pin to +5V via a 4k7 resistor. If an application will not use the MCLR function (ie no switch to 0V as a manual reset) is it OK to simply wire the MCLR pin directly to +5V or does it still need to go via the 4k7 resistor?

If the resistor is essential, can someone please explain why?

Cheers
Barry
