10.4 SPI Signal Description
gnal Description
The four basic signals (MOSI, MISO, SCK, and SS) are described in this
subsection. Each signal function is described for both the master and
slave mode.
10.4.1 Master In Slave Out (MISO)
The MISO line is configured as an input in a master device and as an
output in a slave device. It is one of the two lines that transfer serial data
in one direction, with the most significant bit sent first. The MISO line of
a slave device is placed in the high-impedance state if the slave is not
selected.
10.4.2 Master Out Slave In (MOSI)
The MOSI line is configured as an output in a master device and as an
input in a slave device. It is one of the two lines that transfer serial data
in one direction with the most significant bit sent first.
