12-Channel/8-Channel, Flash-Configurable System
Managers with Nonvolatile Fault Registers
When GPIO1
pose inputs/outputs, read values from the GPIO_ ports
through r1Eh and write values to GPIO_s through r3Eh.
Note that r3Eh has a corresponding flash register, which
programs the default state of a general-purpose output.
See Table 11 for more information on reading and writing
to the GPIO_.

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 14. 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.
