Operating Modes
If the SSB_AUTO bit is set in master mode, the SPI generates the initial falling edge and
the final rising edge of SS for a slave device. The SS output has a falling edge one bit
time before the first edge of SCLK (see the following figure).
12.4.3 Transmission Data
The double-buffered data transmit register allows data to be queued and transmitted. For
an SPI configured as a master, the queued data is transmitted immediately after the
previous transaction has completed. The SPI transmitter empty flag (SPTE) indicates
