Issue about the FIFO of DSPI on MPC5744P

Hello, I have some questions about the FIFO of DSPI.

When I enable the transmit FIFO . Then write the SPI_PUSHR register with the EOQ set to 0 and the transmit FIFO is not full . Will the DSPI start sent the data immediately ? Maybe , it will start send the data when the transmit FIFO is full or the EOQ bit is set.

Am I  right?

 

Regards,

Meng
