Function

PMM supply overvoltage protection falsely triggers POR

Description

The PMM Supply Voltage Monitor (SVM) high side can be configured as overvoltage protection (OVP) using the SVMHOVPE bit of SVSMHCTL register. In this mode a POR should typically be triggered when DVCC reaches ~3.75V.
If the OVP feature of SVM high side is enabled going into LPM234, the SVM might trigger at DVCC voltages below 3.6V (~3.5V) within a few ns after wake-up. This can falsely cause an OVP-triggered POR. The OVP level is temperature sensitive during fail scenario and decreases with higher temperature (85 degC ~3.2V).

Workaround

Use automatic control mode for high-side SVS & SVM (SVSMHCTL.SVSMHACE=1). The SVM high side is inactive in LPM2, LPM3, and LPM4.
