Just use the assembler source as supplied...
Generally, to move over to C, to make the main code easier to modify, you will need to retain the assembler handlers for the interrupts, since the code is very precisely coded regarding the interrupt latency. The rest would translate. The same would apply in any C.

Do you have any experience with AN843? |

No, but I did a similar phase drive sometime ago, and ended up writing the interrupt handlers in assembler, for exactly the reasons outlined in this AN. The timings have to be exact, if it is to work, and the added latency of the handlers in CCS, would not be acceptable.
