10.5 Functional Description
Figure 10-2 shows a block diagram of the serial peripheral interface
circuitry. When a master device transmits data to a slave via the MOSI
line, the slave device responds by sending data to the master device via
the master’s MISO line. This implies full duplex transmission with both
data out and data in synchronized with the same clock signal. Thus, the
byte transmitted is replaced by the byte received and eliminates the
need for separate transmit-empty and receive-full status bits. A single
status bit (SPIF) is used to signify that the I/O operation has been
completed.
