4.2.4 Digital inputs for Low Power Sampler (LPS)
Eight digital input signals, which are generated by a DIP switch array (S3), are provided to trigger
the microcontroller’s Low Power Sampler. The input signals are connected to the microcontroller
via 8 to 1 Multiplexer (IC4). When the DIP switches (S3) are changed during low power mode
(DeepSTOP mode), the microcontroller will wake up.
Please use the following jumper configuration to connect the DIP Switch and multiplexer to the
microcontroller

4.2.5 Pushbutton Switches
Two pushbutton switches (S1and S2) are provided to allow the switching of microcontroller input
port states. The switches are active low and normally open.
