17.6.1 MISO (Master In/Slave Out)
17.6.2 MOSI (Master Out/Slave In)
Technical Data

An overview of the signals is provided in
MISO is one of the two SPI data pins.
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.
MOSI is one of the two SPI data pins.
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.
