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

Revisions Affected

0, A, B, C

Details

This issue only applies when using the LIN as commander. If the LIN attempts to send 0xF0 as a wake-up key, the internal state machine becomes stuck and will not recover, blocking future transmissions.

Workaround

Send an unused LIN header instead of the 0xF0 wake-up signal. The reserved identifier 0x3E or any other unused identifier can be used. The break field within the header acts as a valid LIN wake-up command to other LIN nodes and disables the internal LIN POWERDOWN bit.
