Serial Peripheral Interface (SPI)
MOTOROLA
10.3 Features
SPI features include:
Full-duplex, 4-wire synchronous transfers
Master or slave operation
Bus frequency divided by 2 (maximum) master bit frequency
Bus frequency (maximum) slave bit frequency
Four programmable master bit rates
Programmable clock polarity and phase
End-of-transmission interrupt flag
Write collision flag protection
Master-master mode fault protection capability
10.4 SPI Signal Description
The four basic signals (MOSI, MISO, SCK, and SS) are described here.
Each signal function is described for both the master and slave modes.
NOTE:
Any SPI output line has to have its corresponding data direction register
bit set. If this bit is clear, the line is disconnected from the SPI logic and
becomes a general-purpose input line. When the SPI is enabled, any
SPI input line is forced to act as an input regardless of what is in the
corresponding data direction register bit.
