MSP430F6779: Hex file can be used on 6779A / 67791 / 67791A?

Part Number: MSP430F6779

Hello,

I understand from slaa666a section 5 that TI advises that when migrating from 6779 to 6779A a code recompile is required with the relevant headers. However I do not have the code and am working with an older machine which has 6779.

Is it possible that burning the hex file for 6779 Rev C. -

  1. Will work on 6779A? Assuming AUX PMM has not been used? Is in use?
  2. Will work on 67791? Assuming AUX PMM has not been used? Is in use?
  3. Will work on 67791A? Assuming AUX PMM has not been used? Is in use?

The intent here is should I order the easily available 6779A or 67791A or wait a couple of weeks and get the 6779.

Thanks.
