We have a LIN-Motor Controller project recently and the microcontroller is selected S9S12ZVL. As a LIN-Master, we should send break which contains at least 13 logic 0s based on LIN2.1. We write a logic 1 to SBK(SCICR2) and BRK13(SCISR2), the M(SCICR1) keeps 0 as default. But the LIN bus is at high level all the time, it looks like that we failed to send break. However, We can receive and send datas by the LIN bus. Could you help us? Thanks.
