Analog-to-Digital Converter (ADC)
Low power modes
The WAIT and STOP instruction can put the MCU in low power
consumption standby modes.
WAIT mode
The ADC continues normal operation during 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 ADCH[4:0] bits in the ADC Status and
Control Register before executing the WAIT instruction.
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 after an external interrupt. Allow one conversion
cycle to stabilize the analog circuitry.
