Post by thread:[PIC] 16F684 weak pull-ups

I am doing a 16F684 project. The first page of the datasheet states '12 I/O pins with ... individual weak pull-ups'. I want to use an internal weak-pull up on a port C pin, but I can't find a way to enable a pull-up on C. In fact can find no trace at all of C pull-ups in the datasheet. Do they exist at all?

Wouter, Since there is no WPUC register and there is no pull up FET shown in the port C functional diagrams, I'd consider that statement a 'typo' by Microchip -- you know, a true rarity ;-) Bill Wouter van Ooijen wrote: {Quote hidden}>I am doing a 16F684 project.
