Serial ports offer the following features and capabilities:
• Four operation modes

1. Standard serial
2. Left-justified

3. I S
4. Multichannel
• Two bidirectional channels (A and B) per serial port, configurable
as either transmitters or receivers. Each serial port can also be con-
figured as two receivers or two transmitters, permitting two
unidirectional streams into or out of the same serial port. This
bidirectional functionality provides greater flexibility for serial
communications. Also, two SPORTs can be combined to enable
full-duplex, dual-stream communications.
• All serial data signals have programmable receive and transmit
functions and thus have one transmit and one receive data buffer
register (double-buffer) and a bidirectional shift register associated
with each serial data signal. Double-buffering provides additional
time to service the SPORT.
• An internally-generated serial clock and frame sync provide signals
in a wide range of frequencies. Alternately, the SPORT can accept
clock and frame sync input from an external source.
• Interrupt-driven, single word transfers to and from on-chip mem-
ory controlled by the processor core, described in
