There are three ways to wake-up from sleep mode depending upon control mode, pin or SPI:
- 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 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. Active for both pin and SPI control modes.
- Local wake up through EN being set high for longer than tMODE_CHANGE. Active for pin control mode.
- Local wake up through WAKE pin
- Being set high or low for longer than tMODE_CHANGE. Active for both pin and SPI mode.
- Only active during on-time cyclic sense period. Active for SPI mode.
