If it does screw up a bit, can't you downgrade it again?

Microchip's website is pushing the PUM module upgrade, but many people seem to have problems with it. Is there any reason that an occasional user like myself shouldn't just buy a 17C44 and load it with the last available firmware version (v3.11)? > > Rob > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
