The Bank Select Register (BSR) must be selected to Bank 0 for the port to be initialized. The fol- lowing example uses the MOVLB instruction to load the BSR register for bank selection. EXAMPLE 10-2: INITIALIZING PORTB MOVLB 0 ; Select Bank 0 CLRF PORTB, F ; Init PORTB by clearing ; output data latches MOVLW 0xCF ; Value used to initialize ; data direction MOVWF DDRB ; Set RB<3:0> as inputs ; RB<5:4> as outputs ; RB<7:6> as inputs FIGURE 10-6: BLOCK DIAGRAM OF RB3:RB2 PORT PINS Note: I/O pins have protection diodes to VDD and Vss.
