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 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.
