EXAMPLE 3-1: INITIALIZING PORTA
BCF STATUS, RP0 ; Select Bank 0
CLRF PORTA
; Initialize PORTA by
; clearing output
; data latches
BSF STATUS, RP0 ; Select Bank 1
MOVLW 0Fh
; Value used to
; initialize data
; direction
MOVWF TRISA
; Set RA<3:0> as inputs
; RA<7:4> as outputs. RA<7:6>availability depends on oscillator selection.
MOVLW 03
; Set RA<1:0> as analog inputs, RA<7:2> are digital I/O
MOVWF ANSEL
BCF STATUS, RP0 ; Return to Bank 0
