  13. Configurare modul A/D a) Select port pins as analog inputs (AD1PCFGH<15:0> or AD1PCFGL<15:0>) b) Select voltage reference source to match expected range on analog inputs (AD1CON2<15:13>) c) Select the analog conversion clock to match desired data rate with processor clock (AD1CON3<7:0>) d) Determine how many S/H channels is used (AD1CON2<9:8> an AD1PCFGH<15:0> or AD1PCFGL<15:0>) e) Select the appropriate sample/conversion sequence (AD1CON1<7:5> and AD1CON3<12:8>) f) Select how conversion results are presented in the buffer (AD1CON1<9:8>) g) Turn on ADC module (AD1CON1<15>) 2. Configure ADC interrupt (if required): a) Clear the AD1IF bit b) Select ADC interrupt priority
