4.1.1 Sleep Period
The sleep period configuration switch may configure the sleep period for the MTCH9010. The
MTCH9010 sleep period can be set to 2, 16, or 128 seconds or configured to use the
on-demand wake-up through the WUP_REQ pin when using this switch. The MTCH9010
Evaluation Kit also includes two unpopulated footprints for resistors (R118 and R120)
and a cut-strap, enabling any other sleep period defined in the device’s data sheet.Figure 4-3. Sleep Period Slide

Info: A slide switch is used to
control the power to the USB bridge, see Disabling USB Bridge for more information.
4.2 Reset Button
The MTCH9010 Evaluation Kit features a reset button connected to the MTCH9010's RESET pin. Pressing the button pulls the reset line low and holds the device in reset. When released, the line is pulled high through a pull-up resistor.

4.3 Liquid Detection Threshold
The MTCH9010 Evaluation Kit features a 100 kΩ ±20% linear rotary potentiometer to set the threshold for detecting liquid on the connected sensor. The output from the potentiometer is passed through a low-pass filter to remove high-frequency noise.
