VRFAULT
xxxFAULT, where xxx is the name of the power supply. This
FAULT signal is an OR function of all of the following possible
faults, or just a subset of them depending on the power supply:
• Output under-voltage
• Output over-voltage
• Over-current
• Short-circuit
on what faults are included, and how the supply protects itself
and the load in response to the fault.

ORed together into the BATOCP interrupt signal, which in turn
if unmasked, sets the VRFAULT 1st level interrupt that causes
the PMICINT pin to assert, notifying the SC of a system event.
The SC can service the VRFAULT register and access the
FAULTx registers for more information on which supply caused
the fault. The SC can then take different measures, depending
on the supply in question.
