How to create One Shot Timer ?

Hi Richard,

I suggest to take a look at the CCU4_SLICE_CONFIG APP (Similar option is available in PWM APP also).
There you have an "Single-shot mode" option which should suit your needs perfectly. All it does is setting TC.TSSM bit field to "1". Explanation regarding single shot mode you can find in the accompanying chapter ("Single Shot Mode") in Reference Manual.

Best regards,
Deni
