TMS320F280049: ADCINMXSEL Register???

C2000 buddies,

Working on a 49 application...messing around with the analog subsystem regs and I noticed a register called ADCINMXSEL that is mentioned in the LOCK register (page 1436 of TRM). This is the only place in the entire TRM this register is mentioned. I'm guessing this is just a documentation error and this should actually be ADCDACLOOPBACK. Is that correct? If so please fix :)

Happy Halloween,

Trey

VREGCTL also appears to be missing from the documentation.

Hi Trey!

The VREGCTL and ADCINMXSEL lock bits aren't applicable for this device; I'll submit a ticket to have them removed from the documentation.

There isn't any missing lock bit for the ADCDACLOOPBAC. However, it does require a key to be written to update the register. I don't think you'd want to lock this permanently since it completely overrides the CHSEL of the associated ADC.
