S32K312 sending error using Flexio SPI as master node

[victory]

1.Development environment:S32DS3.5

2.RTD version:4.0.0

3. Refer to the rtd 2.0.3 routine code, detailed code is attached

4. Expected goals such as 4.1 and 4.2

4.1 MOSI only sends data once, while MISO does not receive data

4.2 MOSI triggers the chip selection pin once for every byte of data sent

5. Actual phenomena such as 5.1, 5.2, 5.3, and 5.4

5.1 MOSI keeps sending data, while MISO keeps receiving data

5.2 MOSI triggers the chip selection pin once every 4 bytes of data sent
