4.6 SERIAL PERIPHERAL INTERFACE (SPI)
The on-chip SPI is an optimized serial synchro-
nous interface that supports a wide range of indus-
try standard SPI specifications. The on-chip SPI is
controlled by small and simple user software to
perform serial data exchange. The serial shift
clock can be implemented either by software (us-
ing the bit-set and bit-reset instructions), with the
on-chip Timer 1 by externally connecting the SPI
clock pin to the timer pin or by directly applying an
external clock to the Scl line.
The peripheral is composed by an 8-bit Data/shift
Register and a 4-bit binary counter while the Sin
pin is the serial shift input and Sout is the serial
shift output. These two lines can be tied together
to implement two wires protocols (I2C-bus, etc).
When data is serialized, the MSB is the first bit. Sin
has to be programmed as input. For serial output
operation Sout has to be programmed as open-
drain output.
The SCL, Sin and Sout SPI clock and data signals
are connected to 3 I/O lines on the same external
pins. With these 3 lines, the SPI can operate in the
following operating modes: Software SPI, S-BUS,
I2C-bus and as a standard serial I/O (clock, data,
enable). An interrupt request can be generated af-
ter eight clock pulses.
Figure 34
shows the SPI
block diagram.
The SCL line clocks, on the falling edge, the shift
register and the counter. To allow SPI operation in
slave mode, the SCL pin must be programmed as
input and an external clock must be supplied to
this pin to drive the SPI peripheral.
WARNING
: In all cases, in both slave and master
mode, the SCL pin must always be configured as
input (Reset state).
In master mode, the SCL signal must be generat-
ed by software and output on another free I/O port
pin which must be connected externally to the SCL
input pin.
