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 the LIN bus where the dominant state is held for the 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 tEN.
