'[PIC] 16F684 weak pull-ups'
2005\08\26@161408 by Wouter van Ooijen

face picon face
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?

Doesn't look like it to me. Just port A.

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 ;-)
