TMS320F28068M: Can't write to BAUD Registers (typo in title, should be "TMS320F28069M")

Hello,

I've been attempting to use SCI routines native to Motorware, and shoehorn them into InstaSPIN lab 05b.

Their presence seems to be tolerated by the original Instaspin code, but I can't pick up a single bye from the LCD I'm trying to communicate with.

Started looking around to see what the problem was and found that the SCILBAUD register does not accept anything I'm writing to it (same for SCIHBAUD, but it's immaterial).

I can put a breakpoint right on the line of code where it's being loaded. It appears to execute that line, but the SCILBAUD register remains zero.

I'm pretty sure I've set the SCI up correctly and initialized and enabled everything I need. I can send you the code, if needed.

Thanks,

Dave
