By default, the analog comparator interrupt will be deferred when the cache is disabled for reasons like programming or erasing the flash. Thus the alarm interrupt will not get executed in time, which is not expected in a real-time application.

- :ref:`CONFIG_ANA_CMPR_CTRL_FUNC_IN_IRAM` controls where to place the analog comparator control functions (IRAM or flash). See :ref:`anacmpr-iram-safe` for more information.
- :ref:`CONFIG_ANA_CMPR_ENABLE_DEBUG_LOG` is used to enable the debug log output. Enabling this option increases the firmware binary size.
