by an I2C reading. This is to ensure continuous diagnostics throughout the car-
radio operating time.
– To check the status of the device a sampling system is needed. The timing is
chosen at microprocessor level (over half a second is recommended).
Figure 25. Restart timing without diagnostic enable (permanent) - Each 1ms time, a
sampling of the fault is done
