6.4 COMP_ERR_02

COMP output toggles when DACCODEx is used for hysteresis

Revisions Affected

B

Details

IF using the 8-bit DAC within the COMP module as an input to the COMP,
AND DAC output switches between values placed in DACCODEx,
THEN the COMP output toggles as if immediately crossing the new reference point.
This can happen regardless of the setting of the COMPx.CTL2.DACCTL bit.
This is most commonly seen in applications that utilize the two DACCODEx codes for custom or asymmetrical hysteresis for the COMP module.
Workaround
Utilize the established hysteresis values provided in COMPx.XTL1.HYST register bits.
