Hi everyone, can anyone answer (iii) please?

ln the analog to digital converter (ADC) application or PIC18Fxxxx microcontrollers.there are three different ADC control register which are ADCONO, ADCON1 andADCONZ and there are two result register which are (ADRESH and ADRESLGiven that VREF+ = 9 V and VREF- = 0 V.

(i) Investigate the step size if we are using 10 bit ADC result register.

(ii) Evaluate the value of ADRESH and ADRESL (right justify) if we want to convert 2 V analog value that being connected to the pin ANO.

(iii) Decide the possible value of ADCONO and ADCONI as shown in figure 06(a)(iii) while executing the ADC algorithm in Q6(a)(ii). Assume that the entire higher bit is unutilized and set to become a digital input output pin.

ADCON0
-	-	CHS3	CHS2	CHS1	CHS0	GO/DONE	adon
ADCON1
-	-	VCFG1	VCFG0	PCFG3	PCFG2	PCFG1	PCFG0
