I see you posted this morning on c54x Yahoo Group. Ok that's great, I'm
sure you will get some help.
You sound like a hard-working and industrious student. You are steadily
figuring things out about the DSK 5402. Keep up the good work.
About your question, I don't have any C54x C or asm source for configuring
McBSP0 (DAA telephone interface). You might search TI's website to see if
CSL (chip support library) supports the DSK 5402 -- if so, there will be
some setup routines for the telephony interface. CSL is provided with
CCS, so you may need a specific version of CCS.
