Serial Peripheral Interface (SPI)
MOTOROLA
In a slave mode, the slave select start logic receives a logic low at the
SS pin and a clock at the SCK pin. Thus, the slave is synchronized with
the master. Data from the master is received serially at the MOSI line
and loads the 8-bit shift register. After the 8-bit shift register is loaded, its
data is parallel transferred to the read buffer. During a write cycle, data
is written into the shift register, then the slave waits for a clock train from
the master to shift the data out on the slave
s MISO line.
Figure 10-3
illustrates the MOSI, MISO, SCK, and SS master-slave
interconnections.

10.6 SPI Registers
This subsection describes the three registers in the SPI which provide
control, status, and data storage functions. These registers are:
Serial peripheral control register (SPCR)
Serial peripheral status register (SPSR)
Serial peripheral data I/O register (SPDR)
I/O PORT
SPDR ($000C)
