device is used. Open drain option via register setting.
[Bi-directional Input, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signals, or 2-wire master serial interface to NVRAM in
standalone mode. Open drain option via register setting.
[Bi-directional Input, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signals, or 2-wire master serial interface to NVRAM in
standalone mode. Open drain option via register setting.
[Bi-directional Input, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal when host port is disabled, or data signal for 2-wire
serial host interface.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), slew rate limited, 5V tolerant]
General-purpose input/output signals.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal when host port is disabled, or active-low and open-
drain interrupt output pin.
[Bi-directional, 5V-tolerant]
General-purpose input/output signal when host port is disabled, or clock for 2-wire serial
host interface.
