The Limp Home output is a very useful way to control safety critical functions independent of the microcontroller,
such as turning on or off critical load during a microcontroller failure.
The Limp Home outputs are a very useful way to control safety critical functions independent of the microcontroller,
such as turning on or off critical load during a microcontroller failure.
13.2
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.
Figure 33
13.2.1
The LH_SI output is similar to the Limp Home output. The output is pulsed to
to provide the side indicators frequency. The LH_SI function is active when the Limp Home is active.
Figure 34
13.2.2
The LH_PL/Test pin is an output pin shared with the Test pin function. During SBC Init Mode, the pin is used as
an input, in all other modes, the pin is an output.
The output is pulsed to
the 27W stop lights into an 5W rear light. Refer to
