I was reading about DMA , P2040RM chapter-21. While reading, came across several points those are not clear,
1) Does DMA support to all interface like I2C/SPI/eLBC/ PCIe etc??
2) How to enable DMA in driver code?? How to verify is it enabled or not ??
3) How one can do performance testing with and with out DMA?
Help would be highly appreciated ....
