MDMA size limit of 128

Hello,

I see that MDMA is limited to 128 bytes (BufferTransferLength).

Yet, when using DMA (with HAL_SRAM_Read_DMA for example) we can use larger size (up to 65536).

Yet, I don't see in code that DMA is triggered more than once.

Is it that these multiple transfers are done within controller and are transparent in HAL usage ?

Thanks,

ran
