How to set DFSDM Configuration so that LPF cut-off frequency is 1 KHz on MP34DT01-M using STM32F779NI-EVAL?

Hi, I am evaluating MEMS microphone for our application. I am using on board microphone MP34DT01-M in STM32F779NI-EVAL. I am using DFSDM example in STM32F7cube package and able to hear the speech. Now I want to filter the frequencies higher than 1KHz...

The HAL IRQ for HSEM disables itself. Why?

The HAL driver, HAL_HSEM_IRQHandler() disables itself by clearing bits in it's IER register. I don't want it disabled so I have to re-enable it in my HAL_HSEM_FreeCallback(). Is it desirable that it is disabling itself? I'm using the STM32H755.
