COMP_ERR_01

Comparator output keeps toggling in STANDBY0 mode

Revisions Affected

Rev C

Details

When the comparator inverting input mux (IMSEL) is set to 0 (COMP0_IN0-), and the device operating mode is set to STANDBY0, the comparator output may toggle unexpectedly regardless of the applied input voltages to the comparator.

Workaround

If utilizing comparator in STANDBY0, and applying an external voltage to the negative terminal, utilize channel 1 of the comparator (IMSEL = 1).

If utilizing comparator in STANDBY0, and applying an internal reference voltage (DAC8, VREF, etc.), set IMSEL to a value other than 0 (IMSEL ≠ 0).
