13.6 Queuing Transmission Data
The double-buffered transmit data register allows a data byte to be queued and transmitted. For an SPI
configured as a master, a queued data byte is transmitted immediately after the previous transmission
has completed. The SPI transmitter empty flag (SPTE) indicates when the transmit data buffer is ready
to accept new data. Write to the transmit data register only when the SPTE bit is high.
the timing associated with doing back-to-back transmissions with the SPI (SPSCK has CPHA: CPOL =
1:0).
