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
Hi,
yes, frame is started immediately, unless any of following conditions exist:
• SR[EOQF] bit is set
• Chip is in the Debug mode and the MCR[FRZ] bit is set
• MCR[HALT] bit is set
