There are three ways to wake up from sleep mode:
- Remote wakeup through recessive (high) to dominant (low) state transition on LIN bus. The dominant state must be held for tLINBUS filter time and then the bus must return to the recessive state (to eliminate false wakeups from disturbances on the LIN bus or if the bus is shorted to ground).
- Local wakeup through a low on NWake, which is asserted low longer than the filter time tNWake (to eliminate false wakeups from disturbances on NWake).
- Local wakeup through EN being set high.
