At the risk of dragging this out and becoming the RA4 poster boy (and it's too nice a day to be a-feudin' anyway) The manual covers the usage of other special pins, such as MCLR, OSC, A/D etc. Surely a brief sentence along the lines of "RA4 may require a pullup if used as an I/O pin" is valid information for a manual ? Shoot, put it in the RA4 diagram next to Note 1 about the diodes -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
