12-Channel/8-Channel EEPROM-Programmable
System Managers with Nonvolatile Fault Registers
GPIO1–GPIO6 are programmable general-purpose
inputs/outputs. GPIO1–GPIO6 are configurable as a
manual reset input, a margin disable input, margin-
up/margin-down control inputs, a watchdog timer input

and output, logic inputs/outputs, fault-dependent out-
puts, or as the feedback inputs (INS_) for closed-loop
tracking. When programmed as outputs, GPIOs are
open drain or push-pull. See registers r1Ch to r1Eh in
Tables 4 and 5 for more detailed information on config-
uring GPIO1–GPIO6.
