S32K311 SPI DMA

S32K311 is configured with SPI DMA, but if the DMA channels use 4 and 5, then SPI can trigger a DMA interrupt. If you use other channels, then it will not work. For example, channels 0, 1, 2 and 3 will not work. Use EB to configure it here, RTD3.0. I want to ask why. Thank you. If you want to project, I can upload it.

To add, what's interesting is that this will not happen to the S32K312
