3.24.2.8 Storage and Read of AD Conversion Results
3.24.2.9 Data Polling
Note: In order to detect overruns without omission, read the conversion result storage register's higher-order bits first,
Analog input channel
and then read the lower-order bits next. As this result, receiving the result of OVRn = 0 and ADRnRF = 1 for
overruns existing in the lower-order bits means that a correct conversion result has been obtained.
higher-order/lower-order registers (ADREG0H/L to ADRG7H/L) for the normal AD
conversion (ADREG0H/L to ADREG7H/L are read-only registers)
ADREG0H/L to ADREG3H/L one after another. In other modes, the conversion results
of channels AN0, AN1, AN2, AN3, AN4, AN5,AN6 and AN7 are each stored into

perform a polling on ADMOD0<EOCFN>. After confirming that ADMOD0<EOCFN>
is set to 1, read the AD conversion storage register.
