  "textContent": "A sensor device includes a pressure sensor configured to measure an internal air pressure and generate a sensor signal representative of the measured internal air pressure; a serial peripheral interface (SPI) configured to receive SPI commands; a wake-up terminal configured to output fault signals; and a processing circuit. The processing circuit is configurable between a normal running mode and a low power monitoring (LPM) mode. In LPM mode, the processing circuit is configured to alternate between a sampling phase during which the processing circuit evaluates the sensor signal and a powered-down phase during which the processing circuit is in a low power state. The processing circuit is configured to monitor for at least one SPI communication fault corresponding to information received on the SPI, generate a communication fault signal in response to detecting the at least one SPI communication fault, and output the communication fault signal from the wake-up terminal.",
