Paul,

Previously, I have mentionned a doubt I had about the ANSEL (analog) settings because I agree with you, in DIGITAL, I can have only two states (0 & 1).

Do I have to conclued that the reading of a "3 states ports" can be achieved only by means of software (as stated in the "Tips & Tricks" doc) and that it is not possible by reading the inputs states on the PIC's pins?

I don't care about the Z state.

I would like to read only both "0" and "1" states (2 buttons)...
