Register descriptions

54.3.1.1 Supply Gauge Status register (GR_S)
This status register contains the gauge of the indicated supply or temperature sensor value,
indicating the present state of the voltage or temperature detect events for each of the
supplies. Multiple voltage detect signals for a given voltage are combined to form a single
bit.

VD14 low-voltage detect flag—high voltage 4.00 V supplies.
Read-only low-voltage status flag asserted when any of the supplies fall below the LVD threshold and
17 cleared when all the supplies rise above the corresponding LVD threshold.
VD14 All the 4.00 V supplies are combined to form this bit.
