How can I read a DMA memory buffer n consecutive times? F446RE

Hi evryone,

I try to find a way to read a DMA memory buffer n consecutive times but the issue is that there is a normal mode (1 time) and a circular mode (unlimited time)

I would like to find a way to end the circular mode when I decide, for example to read 4 times the memory buffer and end at the end of the buffer

Is it possible?
