DMA memory to peripheral question.

[simo zz]

Hello,

I have a doubt regarding DMA memory to peripheral ?

Suppose I would like to transfer a memory buffer content to SPIx TX.

When do each transfer occurs ? Every time I change the content of the memory buffer ? Always ?

I cannot find this information into the TRM.

Regards,

Oh, what a fool.

I understand that this is a matter of enabling / disabling the stream.

Thanks.
