I want start the PDB with the Trigger_in0 Signal.

For the trigger_in0 signal I use the Compare Match trigger channel 0 from FTM0 with Trgmux.

TRGF(Bit7) from FTM0.EXTTRIG Register is set., but the PDB counter don't start.

How long must the trigger_in0 Signal pending, that the PDB counter start? 

The FTM trigger channel 0 signal is only one clock cycle.
