This command is provided to the circuit by the LIN Master in order to output the Bemf integrator output
To the SWI output of the chip. Once activated, it can be stopped only after POR. During the Bemf observation, reading of the SWI
state is internally forbidden.
TestBemf corresponds to the following LIN writing frames (type #1).
