PIC16c765 input() problem :(

[tramper2]

hi there~
i'm not a good at english please understand.

my board has 6 switch and its connected with RA0~RA5 of pic16c765.
but it's not working except RA4.
my code like bellows
.......
if(input(PIN_A0)) ~~

so i had changed switch to RB0~RB5 and its worked well
if(input(PIN_B0)) ~~

what is different RA with RB port??

my compiler is ccsc 3.203
thanks

Have you actually set portA, to be used for digital I/O?. By default chips with ADC units, wake up with the analog bits on port A, set to work as analog I/O, usually with the exception of A4.
You need to add:
setup_adc(NO_ANALOGS );

to switch these pins to digital operation.
