8.2 SPI Transfer Formats
During an SPI transfer, data is simultaneously transmitted and received. A serial clock
line synchronizes shifting and sampling of the information on the two serial data lines.
A slave select line allows individual selection of a slave SPI device; slave devices that
are not selected do not interfere with SPI bus activities. On a master SPI device, the
select line can optionally be used to indicate a multiple master bus contention. Refer
to Figure 8-2.
