10 SERIAL PORTS

The processors have eight independent, synchronous serial ports
(SPORTs) that provide an I/O interface to a wide variety of peripheral
devices. They are called SPORT0, SPORT1, SPORT2, SPORT3,
SPORT4, SPORT5, SPORT6, and SPORT7. Each SPORT has its own
set of control registers and data buffers. With a range of clock and frame
synchronization options, the SPORTs allow a variety of serial communi-

industry-standard data converters and codecs. The interface specifications
