SCI Port Connector
The SCI port pins are routed to two connectors:
• Expansion and logic analyzer connectors
• Dedicated SCI port connector
Routing to the expansion - Logic-Analyzer connectors is done to support expansion
boards and application debug while the dedicated connector enables connection to an
application board via a flat cable. To avoid incorrect insertion of the receptacle
connector, keying is provided as one of the pins is cut while its corresponding hole in the
receptacle connector is filled.
The pinout of the SCI dedicated connector is shown in Figure 2-14 on page 2-25.
