MSP430F6779A: Is there a case where AUX0SW,AUX1SW,AUX2SW will always be zero?

Part Number: MSP430F6779A
Other Parts Discussed in Thread: MSP430F67791A

After using for a long time with the power supply switched between DVCC and AUXVCC1.

I found that sometimes abnormal behavior of MCU registers AUX0SW,AUX1SW,AUX2SW will always be zero

What are the possible causes of the problem?

Hi Tink

May I know the initial setting of Auxiliary Supply System (AUX) of MSP430F6779A

on msp430f677xA_aux_03.c of code example: https://www.ti.com/tool/download/SLAC648

it is MSP430F67791A Demo - AUX, Hardware-Controlled Switching, AUXVCC1

AUX0SW,AUX1SW,AUX2SW on AUXCTL0 are not operated. I think they are zero

Thanks
