LIN frame timeout

Hello, I'm using RL78/F13 as a LIN slave and want to pass the LIN conformance test on CANoe.

But in one test case which enlarge the response space to meet the maximum frame time by adding 36 bits, the TER in LEST is always set.

What I want to ask is:

1. Does the judgement of timeout is done by hardware?

2. Can user config this?

3. Is there a possible that hardware misjudge the situation?
