erwise the threshold exceeds the maximum operating
voltage of IN3–IN6.
GPI1–GPI4
The GPI1–GPI4 programmable logic inputs control
power-supply sequencing (programmable outputs),
reset/interrupt signaling, and watchdog functions (see
the Configuring the Watchdog Timers (Registers
3Ch–3Fh) 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.
