The advantage of doing this is now you can very easily set up a single DMA operation that can hit every SPI device on the bus. The controller also lets you specify different timing parameters per chip select. It's one of the most impressive SPI controllers that I have seen on a microcontroller, and it's the only one that I know of with that particular feature. | |
