TPM trigger sinchronization

Good mornig.

I have a very simple application using, the tpm module.

I'm reading 3 thermocouples to control 3 littles oven by the pwm generated from tpm module.

Everything works properly but I need to synchronize the beginning of the pwm with the zero crossing point from the net power.

I get this control, from an input pin selected as input capture.

The target is a FRDM-KL25Z board.

I don't understand how to synchronize it.

Is there anyone to explain me how to this synchronization  ?

Best regards.

Claudo
