AUXPMM Module

Function

AUXVCC1/AUXVCC2 can not be switched back to DVCC

Description

When the system is running with the AUXVCC1 supply after DVCC/AVCC is lost, if the AUXVCC1 voltage goes lower than SVSH setting for POR and above BORH level, the system can not switch back to DVCC after DVCC ramps back up again.
Similarly, when the system is running with the AUXVCC2 supply after DVCC/AVCC is lost, if the AUXVCC2 voltage goes lower than SVSH setting for POR and above BORH level, the system can not switch back to DVCC after DVCC ramps back up again.

Workaround

When the system is running with the AUXVCC1 supply, use SVMH to monitor AUXVCC1 voltage. When AUXVCC1 is lower than the SVMH setting, the program drives the chip into LPMx.5. After DVCC ramps up back again, trigger one of the wake up pins. The power supply could be switched back to DVCC again.

When the system is running with the AUXVCC2 supply, use SVMH to monitor AUXVCC2 voltage. When AUXVCC2 is lower than the SVMH setting, the program drives the chip into LPMx.5. After DVCC ramps up back again, trigger one of the wake up pins. The power supply could be switched back to DVCC again.
