The AMS register set includes several measurement registers that are written to by the PS SYSMON unit using the single-channel mode (sequencer off). These voltage measurements are performed using the unipolar sampling circuit with a 0 to 3V range and do not have alarms or minimum/maximum registers.

The AMS measurement register names for each voltage node are listed in Table: Measurement Registers in AMS Register Set, and are accessed starting at memory location 0xFFA5_0060.
