Fault1 and Fault2
GPIO1 to GPIO8 are configurable as dedicated fault out-
puts, Fault1 or Fault2. Fault outputs can assert on one or
more overvoltage, undervoltage, or early warning condi-
tions for selected inputs, as well as the secondary over-
current comparator. Fault1 and Fault2 dependencies
are set using registers r36h to r3Ah. See Table 10. When
a fault output depends on more than one MON_, the
fault output asserts when one or more MON_ exceeds a
programmed threshold voltage. These fault outputs act
independently of the critical fault system, described in
the Critical Faults section.
