Hi here SET from Argentina:

Sorry if this is allready answered but the mails come here with some delay:

Alex: PORTA,4 is open collector, put a pull-up resistor suitable for your case
(20K is the value used by Mchip as weak pull-up in port B INs (not outs) that's
more than enough to get it working, but if you plan to handle a transistor you
will need a lower resistor).

bye SET
