MSP430F6779A: Which auxiliary power switch is chosen when mixing software and hardware control?

Hi Tink 

Could you please share your initial setting of Auxiliary Supply System (AUX) mixing software and hardware control

So far, I only can find the code example of Software-Controlled Switching, AUXVCC1

the code example is msp430f677xA_aux_01.c of https://www.ti.com/tool/download/SLAC648

Thanks

    if ((AUXCTL0_L & LOCKAUX_L) == LOCKAUX_L)   // Auxiliary is locked because of core power down?
    {
        AUXCTL0_L &= ~LOCKAUX_L;                // Release Auxiliary module from core power down
    }

    AUXIE     = 0x0000;                         // AUXIE Disable.
    AUXCTL2   =  (AUXMR_0 | AUX0LVL_6 | AUX1LVL_5 | AUX2LVL_0);
                                                // AUXCTL2    Auxiliary supply monitoring rate: 0.
                                                //            AUX0LVL : 3.0V.
                                                //            AUX1LVL : 2.7V.
                                                //            AUX2LVL : 0.0V.
    AUXIFG   &= ~(AUX0SWIFG | AUX1SWIFG | AUX2SWIFG | AUX0DRPIFG | AUX1DRPIFG | AUX2DRPIFG | AUXMONIFG | AUXSWNMIFG);
                                                // AUXIFG
    AUXCTL1 |=   (AUX0MD | AUX2MD);
    AUXCTL1  =   (AUX0MD | AUX2MD | AUX0OK);

Hi Tink 

Thanks for your code. I will found some time to check this setting.

Can I confirm the hardware setting? there are AUX0LVL and AUX1LVL.

no voltage on  AUX2LVL?

// AUXCTL2 Auxiliary supply monitoring rate: 0.
// AUX0LVL : 3.0V.
// AUX1LVL : 2.7V.
// AUX2LVL : 0.0V.

Thanks

Yes, there are AUX0 and AUX1, no voltage on AUX2.

Hi Tink

I need the board to check the code. for example, the target board or EVM.

May I know which board you are using.

if you are using EVM430-F6779, Please check Implementation of a Three-Phase Electronic Watt-Hour Meter Using MSP430F677x(A) (Rev. G)

Thanks!

It's not an EVM, it's a customized board.

Hi,

Are there any updates (This setting is currently used, so i would like to know its behavior)

Thanks.

Hi Tink

I think I need more time to check this power setting on the target board

Thanks
