11.6 Functional Description
11. Serial Expansion Interface (SEI)
11.6 Functional Description
from its MISO pin to the master device’s MISO pin. This means that data are exchanged between master and slave
via full-duplex communication, with data output and input operations synchronized by the same clock signal. After
end of transfer, the transmit byte in 8 bit shift register is replaced with the receive byte.
Figure 11-4 shows how the SEI master and slave are connected.
When the master device sends data from its MOSI pin to a slave device’s MOSI pin, the slave device returns data
