Hello dear community!
We are using TLE9862 in our project. There are some cases when motor is triggered and after this MODE_FB stay in 0x05 (Receive only mode). We need 0x07 (LIN Normal Mode). Does anyone faced with same issue? How to reset back ? After MCU reset everything is working fine.

Best regards

Dmitrij

Hi @dmitrij,

Lin receive-only mode (LROM) to Lin Normal mode(LNM) can be set by executing:

– CTRL_STS.MODE is configured to LIN Normal Mode and
– Feedback signals of Mode and Slope Mode are ok (see Chapter 20.3.2) and
– VS undervoltage flag (SYS_SUPPLY_IRQ_STS.VS_UV_STS) is not set and
– LIN transceiver CTRL_STS.OT_STS and CTRL_STS.OC_STS are not set and
– no CTRL_STS.TXD_TMOUT is set

 

For more details please refer to the section 20.3.1 LIN Transceiver Modes in document : TLE986x-User-Manual-055

Please let us know if you need further details.

 

Thanks,

Krupashankar
