Hello

    Now I use TJA1128  as the Lin controller, and I want to enter the config mode of TJA1128,I see the data sheet, only when the CRC fail, TJA1128 will enter into config mode.

   So how to make CRC errors?

Hello,

NXP delivers the TJA1128 in the Config mode as initial mode.

If the device is programmed and is in Normal mode (or other) you can enter Config only by restoring factory preset value. The sequence is shown in Fig. 23 of the attached AH1801.

Best regards,

Tomas
