3.5.4 Serial Ports
The 5509 Serial Port1 and Serial Port2 each consists of six signals that support two different modes:
•
McBSP mode: all six signals of the McBSP are routed to the six external signals of the serial port.
•
MMC/SD mode: all six signals of the MultiMedia Card/Secure Digital port are routed to the six external
signals of the serial port.
