POR

OFF

Read CS/WAKE.

If low, then READY.

If high, READY1 mode.

Sample FAULT/SLPS and

select slope

Ready

OFF

If CS/WAKE rising edge, then

Operation mode.

Bus Off state

Ready1

OFF

If CS/WAKE falling edge,

then READY mode.

Bus Off state

Operation

If CS/WAKE falling edge,

then Power down.

Normal Operation mode

Power-down

OFF

On LIN bus falling, go to

READY mode.

On CS/WAKE rising edge, go

to Operational mode

Low-Power mode

Note:

After power-on, CS will not be sampled until VREG has stabized and an additional 600 µs has elapsed. The

microcontroller should toggle CS approximately 1mS after RESET to ensure that CS will be recognized.
