56.6.5.4 Leading-Edge Blanking (LEB)

PWM channels 1 and 2 support leading-edge blanking. Leading-edge blanking masks the external trigger input when a transient occurs on the corresponding PWM output. It masks potential spurious external events due to power transistor switching.

The blanking delay on each external trigger input is configured by programming the LEBDELAYx in the PWM Leading-Edge Blanking Register.

The LEB can be enabled on both the rising and the falling edges for the PWMH and PWML outputs through the bits PWMLFEN, PWMLREN, PWMHFEN, PWMHREN.

Any event on the PWMEXTRGx input which occurs during the blanking time is ignored.
