Full alert identifier: PMR_a101_hwVoltageMonitorTrip
Alert description
The Error Signal Module (ESM) Voltage Monitor (VMON) module detected under/overvoltage on one or more of the following rails: VDDA 1.8V, VBGAP 0.9V, VDD 1.2V, IO BIAS, external supply monitor, VDDA 3.3V, ADC0, ADC1/2, ADC3/4, or ADC_R0/1.
Potential impact
The processor is put into a safe state as a result of the under/overvoltage.
Set condition
Any of the relevant ESM VMON status registers indicate under/overvoltage.
Clear condition
All the relevant ESM VMON status registers indicate nominal voltage.
