Can the PWM generated by the FTM be set to generate a pre trigger on both its rising edge and falling edge to trigger the PDB?

Hi,

only rising edge of input trigger asserts PDB pretrigger

Input trigger is selected using Trigger mux, from FTM, initialization and external triggers can be selected. External trigger can be generated several times in PWM period, depends on mode used. Thus PDB can be triggered at both PWM edges.

BR, Petr
