There are three ways to wake-up the TLIN2021A-Q1 from sleep mode:
- Remote wake-up initiated by the falling edge of a recessive-to-dominant state
transition on the LIN bus where the dominant state is held longer than
tLINBUS filter time. After the tLINBUS filter time has
been met a rising edge on the LIN bus going from dominant-to-recessive initiates
a remote wake-up event. The pattern and tLINBUS filter time used for
the LIN wake-up prevents noise and bus stuck dominant faults from causing false
wake requests.
- A local wake-up event due to the EN pin being set high for t > tMODE_CHANGE.
- A local wake-up event due to a change in voltage level on the WAKE pin for t > tWAKE
