How to send 32-bit SPI using mpc5477 chip

hi,

I use Simulink to build the model. Its name is NXP_ MBDToolbox_ MPC57xx.

I want the master to send 32-bit data to the slave, but it only supports sending 16-bit data.

When I adjust the transfer size to 32, the oscilloscope displays abnormal.When I adjust the transfer size to 16, if I send 16 bits twice in a row, there will be a delay between SCKs.In the attachment are my model and the oscilloscope image when it is sent twice in a row.
