10.4 SPI Signal Description
The four basic signals (MOSI, MISO, SCK, and SS) are described in the
following paragraphs. 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.
