Hello,
I have two questions regarding DMA use on XMC4xxx:
1. Is it allowed to read peripheral register USIC0->RBUF by DMA with source width configured as 8bit?
2. Is it correct to expect when reading USIC0->RBUS by DMA with source width 32bit and destination width configured as 8bit that only lower 8bits of RBUF are transferred to destination memory?
thank you
rum
