For More Information On This Product,
In master mode, MISO is the data input.
In slave mode, MISO is the data output and is three-stated until a
master drives the SS input pin low.
In bidirectional mode, a slave MISO pin is the SISO pin (slave
in/slave out).
In a multiple-master system, all MISO pins are tied together.
In master mode, MOSI is the data output.
In slave mode, MOSI is the data input.
In bidirectional mode, a master MOSI pin is the MOMI pin (master
out/master in).
In a multiple-master system, all MOSI pins are tied together.
