The datasheet for the DaVinci TMS320DM6446 lists a number of registers titled MDCFGn where n goes from 0 to 40. Each register is described as a configuration but I cannot find any documentation on what these registers do or how they are used. The TMS320DM644x ARM Subsystem Reference Guide (SPRUE14A) talks about MDSTAT and MDCTL registers but the MDCFG registers are conspicuously absent.
Where can I find information on these?
