Hello, I am currently using the S32K314 chip in conjunction with the MC33FS6500LAE for LIN driver development. I have already configured the LIN part of the MCU, but the bus has not received any data. Could you please tell me if the MC33FS6500LAE chip requires a driver to be written for it to use LIN? If it does, I only have a data sheet about this chip. What should I do? This is very important to me and I am looking forward to your reply.
Hello, currently I have set the LIN mode of the MC33FS6500LAE chip to normal mode. It is possible to send complete frames using the master mode. However, there are still issues with receiving the response from the slave node in the master mode. Could you please tell me which parts of this chip need to be configured for receiving the response?
Hello,
Yes, the FS65 requires SPI communication for initialization, watchdog handling and enabling the LIN transceiver. The example initialization flow chart in our AN14879 illustrates a CAN_LIN_MODE write at the end of the initialization sequence after closing the INIT_FS window (256ms after reset).

This is my first time using this chip. I'm currently reading the data manual of this chip. Could you please tell me how to set the LIN mode of this chip to normal mode? Is it through SPI?
Hello,
By default the LIN mode is "Sleep/wake-up capability".
What you need to do is to change the mode to "Normal" by setting LIN_MODE_1:0 = 0b11:
Hope it helps.
BRs, Tomas
