SERIAL PERIPHERAL INTERFACE (SPI)
SERIAL PERIPHERAL INTERFACE (Cont’d)
10.7.4 Functional Description

(SPI) block diagram.
This interface contains 4 dedicated registers:
Refer to the SPCR, SPPR, SPSR and SPDR reg-
isters in
10.7.4.1 Master Configuration
In a master configuration, the serial clock is gener-
ated on the SCK pin.

– A Data Register (SPDR)

In this configuration the MOSI pin is a data output
and the MISO pin is a data input.
Transmit Sequence
The transmit sequence begins when a byte is writ-
ten the SPDR register.
The data byte is parallel loaded into the 8-bit shift
register (from the internal bus) during a write cycle
and then shifted out serially to the MOSI pin most
significant bit first.
When data transfer is complete:
During the last clock cycle the SPIF bit is set, a
copy of the data byte received in the shift register
is moved to a buffer. When the SPDR register is
read, the SPI peripheral returns this buffered val-
ue.
Clearing the SPIF bit is performed by the following
software sequence:
1. An access to the SPSR register while the SPIF
2. A read of the SPDR register.
Note: While the SPIF bit is set, all writes to the
SPDR register are inhibited until the SPSR regis-
ter is read.
– The SPIF bit is set by hardware
– An interrupt is generated if the SPIS and SPIE
bit is set
bits are set.
