GPI1–GPI4
The GPI1–GPI4 (General-Purpose Input) programmable
logic inputs control power-supply sequencing (pro-
grammable outputs), reset/interrupt signaling, and
watchdog functions (see the
Configuring the Watchdog
Timer section). Configure GPI1–GPI4 for active-low or
active-high logic (Table 5). GPI1–GPI4 internally pull
down to GND through a 10A current sink.
MR
The manual reset (MR) input initiates a reset condition.
See Table 6 to program the PO_ outputs to assert when
MR is low. All affected programmable outputs remain
asserted (see the
Programmable Outputs section) for
their PO_ timeout periods after MR releases high. An
internal 10A current source pulls MR to DBP. Leave
MR unconnected or connect to DBP if unused.
