The Limp Home output is an active LOW open drain transistor, please refer to
to connect at least an external pull-up resistor at.
The Limp Home output is activated due to a failure condition or via SPI, see
the Limp Home cannot be activated and remains as a high impedance.

13.2.1
The Test pin is used to set the SBC chip into SBC Software Development Mode. When the Test pin is connected
to GND, the SBC starts in SBC Software Development Mode. When the pin is left open, or connected to
SBC starts into normal operation. Please refer to
(switched ON only during SBC Init Mode) to prevent the SBC device from starting in SBC Software Development
Mode during normal life of the vehicle, as for example when the battery has been disconnected. To avoid
disturbance, the Test pin is monitored during the Init Mode (from the time
pin is low for the Init Mode time, Software Development Mode is reached. The mode is stored during the complete
time where
