There are two ways to wake up from sleep mode:
- Remote wake up initiated by the falling edge of a recessive
(high) to dominant (low) state transition on LIN bus where the dominant
state is be held for tLINBUS filter time. After this
tLINBUS filter time has been met and a rising edge on the LIN
bus going from dominant state to recessive state initiates a remote wake up
event, eliminating false wake ups from disturbances on the LIN bus or if the
bus is shorted to ground.
- Local wake up through EN being set high for longer than
tMODE_CHANGE.
