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:

In C9A mode, 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.
