Before any operation, driver interruption is de-asserted to prevent race condition between TX and RX. The NCI over SPI header is added in front of NCI packet. If acknowledged mode is set, CRC-16-CCITT is added to the packet. Then the packet is forwarded to SPI module to be sent. A delay after the transaction is added. This delay is determined by the driver during nci_spi_allocate_device() call and can be 0. After data has been sent, driver interruption is re-asserted. If acknowledged mode is set, nci_spi_send will block until acknowledgment is received.
