PRELIMINARY DATA SHEET
24. Serial Synchronous Peripheral Interface (SPI)
A SPI module provides a serial input and output link to exter-
nal hardware. An 8 or 9 bit data frame can be transmitted in
synchronism to an internally or externally generated clock.
The SPI module can be operated via direct access or via
DMA.
The number of SPIs implemented is given in Table 24–1. The
“x” in register names distinguishes the module number.
