ADB is ADC data buffer to store AD converter result. The ADB is only 8-bit register including bit4~bit11 ADC data. To
combine ADB register and the low-nibble of ADR will get full 12-bit ADC data buffer. The ADC buffer is a read-only
register. In 8-bit ADC mode, the ADC data is stored in ADB register. In 12-bit ADC mode, the ADC data is stored in
ADB and ADR registers.

Note: ADB[0:11] value is unknown when power on.
