inactive while the controller is operational, i.e. it has passed all checks after
startup and no failure was detected.
If the output does not provide the alternating signal it may indicate following:

15.2.1.55 Binary output: BTB status
Related FW
3.0
Description
This output indicates the BTB position, how it is internally considered in the
controller. The position is based on BTB feedback input and optionally also
on the BTB fdb neg input.
If only the positive feedback input is used the output mirrors the
feedback.
If both feedbacks are used and they match each other the output
indicates the BTB position according to the feedbacks.
If both feedbacks are used, however they do not match each other,
the output remains in previous position when they matched.
The output can be used for indication of the BTB position.
