Due to the noise or other interference, the input signal may fluctuate around the threshold voltage, causing the output to switch rapidly and erratically. This can lead to false triggering. Comparator blanking mode introduces a brief delay between the time the input signal crosses the threshold voltage and the time the output changes state.
During this delay period, the comparator ignores any further changes in the input signal and maintains its current output state. This feature is mainly for uses cases like PWM waves indicated by a timer in motor drive, power control, and so on.
The control bits BLANKSRC in the register CTL2 can be used to configure disable or which source should be working on blanking mode. Refer to the data sheet of the device to see the specific blanking sources supported.
