Analog-to-Digital Converter (ADC)
15.5.1 Wait Mode
The ADC continues normal operation in wait mode. Any enabled CPU interrupt request from the ADC can
bring the MCU out of wait mode. If the ADC is not required to bring the MCU out of wait mode, power
down the ADC by setting the ADCH[4:0] bits to logic 1’s before executing the WAIT instruction.
15.5.2 Stop Mode
The ADC module is inactive after the execution of a STOP instruction. Any pending conversion is aborted.
ADC conversions resume when the MCU exits stop mode. Allow one conversion cycle to stabilize the
analog circuitry before attempting a new ADC conversion after exiting stop mode.
15.6 I/O Signals
The ADC module has eight channels shared with port A I/O pins.
