STPMS2L settings

STPMS2L operating parameters are set through its configuration terminals MS0, MS1, MS2
and MS3. On STM32L476G-EVAL, both devices are configured as follows:
•
voltage channel range: differential voltage +/- 300mV
•
current channel range: differential voltage +/- 300mV
•
internal voltage reference is used
•
input bandwidth: 0 to 1 kHz
•
temperature compensation: flattest +30ppm/°C
•
DAT output: voltage and current samples multiplexed
• DATn output: not used
• HW mode selected for settings

STPMS2L power metering

STPMS2L in U3 position simulates low-voltage AC power metering, with capacitive load
impedance, to give different phase to voltage and current.
