Hi,

I was trying to configure HRTIM of STM32F334C8T of my STM32F3348DISCOVERY board with STM32Cube and encountered an issue.

I set External Event 6 as:

- Source : External Pin (source 1)

- Polarity : high

- Sensitivity : rising edge

and I want to apply an external event filtering on this event of type Blanking with Latch enabled.

The issue is that I cannot set latch enabled with an external pin source for external event but only latch disabled.

I don't understand why this option is disabled, nothing in Reference Manual mentions that latch is not useable in this case and even ST example HRTIM_TM_PFC use this feature with external pin for external event.

Is there a reason that the feature cannot be selected in this case in STM32Cube ?

Thanks
