LIN: LIN Unable to Wake Up Using 0xF0 Wake-Up Key

Revisions Affected

0, A, B

Details

When 0xF0 is sent as a wake-up key, the LIN state machines become stuck. This occurs because the LIN does not have sufficient time to detect a valid sync break field before the rising edge of the receive (RX) pin arrives. Therefore, 0xF0 is an invalid wake-up key.

Workaround

Unused LIN Header Transmission

Send an unused LIN header instead of the wake-up signal. The break field within the header acts as a wake-up signal and disables the POWERDOWN bit during the wake-up process. This ensures that the LIN transmissions following LIN wake-up are unaffected.
