| Code: |
setup_adc_ports(sAN0|sAN1|sAN2);

Yes, that's the way it works, except that you specified A0, A1, and A3,
so you should use sAN3 as the last parameter, and not sAN2. Example:
| Code: | | setup_adc_ports(sAN0|sAN1|sAN3); |

Thank you PCM:
How about if I want to set A0, A1, A2 as ADC port, A3 as digital input A4, A5 as output?
Is it like
| Code: |
set_tris_a(0b00001111); setup_adc_ports(sAN0|sAN1|sAN2);
|
first set a0-a2 as output then set it as adc input right? |

You can't always do all combinations. The place to look is the chip's data sheet. It will tell you what is possible.
