SPI/LVDS
Interface Select Pin. Logic low selects SPI-compatible interface mode; logic high selects LVDS interface mode.
This pin has a pull-down current source (~350 μA). In LVDS interface mode, the CPOHx and CPOLx pins default
to differential interface pins.

DUTGND
DUT Voltage Sense Input (Low Sense). By default, this input is shared among all four PMU channels. If a DUTGND
input is required for each channel, the user can configure the GUARDINx/DUTGNDx pins as DUTGND inputs for
each PMU channel.
