Data Sheet
6.13.2. Single ADC Conversion
The single conversion command performs an ADC conversion on the channel specified as part of the command. Once complete, a flag
is set, and the 8 bit data for the conversion is available in its associated register.

Function
Perform an ADC on the external input 1
Perform an ADC on the external input 2
Perform an ADC on the internal temperature sensor
Perform an ADC on the Internal battery voltage
Perform an ADC on the receiver RSSI
Perform an ADC on the loop filter
6.13.3. Continuous ADC Conversion
This command can be given to the radio and operate in parallel with transmit or receive. This mode can also be entered into from an
idle state. In this mode the specified ADC channel is continuously converted, and its associated register is continuously over written.
