I'm debugging on a 5509a board, via an XDS100, rev B emulator, using CC v5.4.
I'd like to see where the XRDY bit of the SPCR2 McBSP0 register is being reset. Can I set a watchpoint to that I/O address? (From what I've seen, it seems watchpoints can only be set in Data memory.) Or is there another way of identifying the point in the code where it is reset?
