Hi,

S32K3 devices offer enhanced RXFIFO for some FlexCAN instances. Enhanced RXFIFO allows using RXFIFO/DMA features even if CAN FD is enabled.

Refer to FlexCAN chapter of device Reference Manual to know more about this enhanced RXFIFO.
Example using enhanced RXFIFO is posted at https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K344-FlexCAN-Ip-TX-RX-EnhanceRXFIFO-test-S32DS3-4/ta-p/1536225 utilizing RTD low level driver.

BR, Petr
