Not used
IN2 input impedance. 0 = normal mode. 1 = high-Z mode, with a 0.1667V to 1.0167V range in
3.3mV increments.
IN3 input impedance. 0 = normal mode. 1 = high-Z mode, with a 0.1667V to 1.0167V range in
3.3mV increments.
IN4 input impedance. 0 = normal mode. 1 = high-Z mode, with a 0.1667V to 1.0167V range in
3.3mV increments.

3.3mV increments.
IN6 input impedance. 0 = normal mode. 1 = high-Z mode, with a 0.1667V to 1.0167V range in
3.3mV increments.

3.3mV increments.
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 10μA 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 10μA current source pulls MR to DBP. Leave
MR unconnected or connect to DBP if unused.
