TMS320c6424 EVM - emif

This is a tough question to answer because it depends on what you want to do.

There isn't a typical (functional) CSL for the C6424 like there was for some of the older processors. The C6424 offering includes PSP drivers and a register-layer CSL you can find here. The EMIF is basically a "passive" peripheral in the sense that you generally only need to program it once and then use it indefinitely without modifying the registers.

With that said, once the EMIF is configured it can be used by simply accessing the external memory ranges through pointers or the EDMA.
