Pin descriptions

2.1

This pin is used to provide the power to the device. A 0.1 µF decoupling ceramic capacitor is

2.2

This is the supply ground for the device.

2.3

Primary Smart Reset™ input (SR0)

The primary push-button Smart Reset™ input, active-low pin is connected to the push-

button switch. The input logic voltage levels are set to a fixed voltage level and have no

internal pull-up resistor.

2.4

Secondary Smart Reset™ input (SR1)

The secondary push-button Smart Reset™ input, active-low pin is connected to the second

push-button switch. The input logic voltage levels are set to a fixed voltage level and have no

internal pull-up resistor. Keeping both Smart Reset™ inputs SR0 and SR1 active for longer
