3.11. Analog to Digital Converter (ADC)
Two Analog to Digital Converter inputs, ADC0 and ADC1, are provided by AirPrime HL77xx modules.
These converters are 8-bits resolution ADCs ranging from 0 to 1.8V.
Typical ADC use is for monitoring external voltage, wherein an application is used to safely power OFF
an external supply in case of overvoltage.
Refer to the following table for the pad description of the ADC interface.
