I used S32K344 and SJA1105 for the development of network communication and MII interface. The actual debugging found that the data received by the network card was abnormal. For example, the data actually sent by me was 0x34, 0x23, while the data received by the S32K344 network card was 0x33, 0x44, 0x22, 0x33. Every 4 bits are repeated. How do I fix this?
