Figure 4.41 ADC Operation for Align bit
SET ADCM2
Select ADC Clock & Data Align Bit.
SET ADCM
ADC enable & Select AN Input Channel.
Converting START
N
AFLAG = 1?
Y
READ ADCRH/L
ADC END
Start ADC Conversion.
If Conversion is completed, AFLG is set “1” and ADC
interrupt is occurred.
After Conversion is completed, read ADCRH and ADCRL.
