MPC5744P FlexPWM offers possibility to synchronize the FlexPWM modules via external synchronization.

Attached is example application how to properly synchronize 2 FlexPWMs modules:

FlexPWMs run with motor control clock (MOT_CLK) with 100MHz frequency:

PWM period is 20MHz with 50% duty cycle:

Below is figure representing External synchronization of 2 PWM (on this frequency I have 2 clocks delay between synchronization)

With adjusted FlexPWM0 channel A0 init value by 2 clocks I have reached following results:
