I want to use DMA to transport data between RAM and a SPI device, and the MCU is the SPI master. I read "an4147" document and demonstration code, and I think it just use four DMA channel to simulate a SPI controller. I read the MPC5605 datasheet, and I understand that DMA can be triggered by internal SPI controller through TFFF and RFDF. Do I understand this correctly? Can you provide a demonstration code or some guide as detailed as you can, thank for your help.
