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 held for tLINBUS filter time. After this tLINBUS filter time has been met and a rising edge on the LIN bus going from dominate 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.
