Chapter 31 Analog-to-Digital Converter (ADC)
31.4.10 MCU wait mode operation
Wait mode is a lower power-consumption standby mode from which recovery is fast
because the clock sources remain active. If a conversion is in progress when the MCU
enters Wait mode, it continues until completion. Conversions can be initiated while the
MCU is in Wait mode by means of the hardware trigger or if continuous conversions are
enabled.
The bus clock, bus clock divided by two, and ADACK are available as conversion clock
sources while in Wait mode. The use of ALTCLK as the conversion clock source in Wait
is dependent on the definition of ALTCLK for this MCU. Refer to the Chip
Configuration information on ALTCLK specific to this MCU.
If the compare and hardware averaging functions are disabled, a conversion complete
event sets the COCO and generates an ADC interrupt to wake the MCU from Wait mode
if the respective ADC interrupt is enabled (AIEN=1). If the hardware averaging function
is enabled, the COCO will set (and generate an interrupt if enabled) when the selected
number of conversions are completed. If the compare function is enabled, the COCO will
set (and generate an interrupt if enabled) only if the compare conditions are met. If a
single conversion is selected and the compare trigger is not met, the ADC will return to
its idle state and cannot wake the MCU from Wait mode unless a new conversion is
initiated by the hardware trigger.
31.4.11 MCU Normal Stop mode operation
Stop mode is a low power-consumption standby mode during which most or all clock
sources on the MCU are disabled.
31.4.11.1 Normal Stop mode with ADACK disabled
If the asynchronous clock, ADACK, is not selected as the conversion clock, executing a
stop instruction aborts the current conversion and places the ADC in its idle state. The
contents of the ADC registers, including Rn, are unaffected by Normal Stop mode. After
exiting from Normal Stop mode, a software or hardware trigger is required to resume
conversions.
