2.6 ADC
A8000 provides 2 auxiliary ADCs (General purpose analog to digital converter, ADC1, ADC2) for
measurements of analog signal such as battery temperature, battery id and environment temperature
etc. It should be noted that only voltage no more than 2.0V could be measured correctly. Table2-9
defines the 2 ADC pins.
