3.22.2.8 Storage and Read of AD Conversion Results
3.22.2.9 Data Polling
Note: In order to detect overruns without omission, read the conversion result storage register's higher-order bits first,
and then read the lower-order bits next. As this result, receiving the result of OVRn
overruns existing in the lower-order bits means that a correct conversion result has been obtained.
higher-order/lower-order registers (ADREG4H/L to ADRG7H/L) for the normal AD
conversion (ADREG4H/L to ADREG7H/L are read-only registers)

is set to 1, read the AD conversion storage register.
