DMA maximum frequency supported
Hi guys, I'd like to ask you a question about the use of the DMA....
For some reasons I need to transfer some data from a status register to the internal memory....the status register value is changed at a frequency of 33MHz (8 digital input pins are linked to the status register).
The problem is that apparently the transfer operation performed by the DMA doesn't fit this high speed since I get less sample than expected (it should fit something like 6 or 7 MHz)....so my question would be:
is there a maximum clock frequency supported by the DMA (by the drq input)?
Thank you very much in advance!! ;)
