    NO, as set all port a inputs.
    TRISB=%00000000
    TRISC=%11110000
    Will PBP handle my concerns?
    Comments will be appreciated.
    Ok, all port b outputs upper half of PortC as inputs,
    set ADCON0=0 , CMCON=7 , and remember RA4 is open drain and requires a pullup resistor.

    Default PortA good to go

    It looks like I'm good to go. Also thanks for mentioning ADCON0 and CMCON, I wasn't sure about that.
    Thanks Joe
