I
Active-low hardware reset signal. The reset signal must be held low for at least 1
μ
S.
[Input, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal or PWM0. Open drain option via register setting.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal or PWM1. Open drain option via register setting.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal or PWM2. Open drain option via register setting.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal. Open drain option via register setting. This pin is also
connected to Timer 1 clock input of the OCM.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal. Open drain option via register setting. This pin is also
connected to the OCM UART data input signal by programming an OCM register. Add
10K Pull-up to VDD_3.3.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal. Open drain option via register setting. This pin is also
connected to the OCM UART data output signal by programming an OCM register. Add
10K Pull-up to VDD_3.3.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal. This is also active-low interrupt input to OCM and is
directly wired to OCM int_0n.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal. Open drain option via register setting.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal. Open drain option via register setting.
[Bi-directional, Schmitt trigger (400mV typical hysteresis), 5V-tolerant]
General-purpose input/output signal, or ROM write enable if a programmable FLASH
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.
