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 ?
