4.4.2 Ground TP1 [8]
This test point offers the common ground potential for the board by an easily
accessible Test point.
4.5 Integrated Circuits
4.5.1 Renesas ZSSC4161D IC [6]
The measured sensor value from the external or internal sensor circuit is
processed via a Renesas Signal Conditioner IC which improves the signal and
transforms the value according to the SENT protocol standard. Besides that, the
IC performs several diagnostics on the sensor circuit, which are covered partly by
the board hardware.

4.6 Circuits
4.6.1 Board Sensor Circuit [4]
The board is equipped with a built-in sensor circuit. The circuit simulates a
pressure or torque sensor by using a resistive Wheatstone Bridge. The
resistance can be modified by a potentiometer.
The processing of the measured signal is carried out by the Signal Conditioner
IC, which transforms the value according to the SENT protocol standard.
