Diagnostic Mode

In default configuration, the sensor is in communication mode. Pin 6 acts as single wire UART

interface connection and can be used to configure all relevant customer setting.

During the programming process, it is possible to enable the diagnostic function by programming the

“Diag_EN” bit in the CONFIG2 Register – 0x17. In that case, pin 6 is acting as diagnostic output after

the next power on reset of the sensor.

The diagnostic function checks if the status of the OTP register is still valid and correct. It is directly

linked to the ECC_error status 1 and 2 (ECC_STATUS Register

– 0x51).
