+   :name: NXP S32 Peripheral Sensor Interface (PSI5)
+
+   Use NXP S32 Peripheral Sensor Interface (PSI5).
+
+Overview
+********
+
+The sample application shows how to use NXP S32 Peripheral Sensor Interface (PSI5):
+
+* Receive data
+* Transmit data
+
+Requirements
+************
+
+This sample requires connecting a wire between pin PA6 (data reception pin) and sensor.
