Task on GTM DPLL loss lock callback in ECU?

[jmary]

Anyone here do ECU project with GTM on SPC57?

what task/function should I add on loss lock callback of the GTM DPLL? I saw some samples project, they switch to half cycle ( 360 degree ) on the loss lock callback event. but I still have no clue the benefit of this such task. perhaps anyone here have some suggestions.

Yes, I had. The problem with the sample code there, after lost lock event the code then reinit the GTM. But then the pmt register became invalid.
