RS-232 UART Connector (P11)
Serial interfaces are available at connector P11. It is a double deck RS-232 female connector. The upper
port is UART1 and the lower port is UART2. By default, UART1 is used.

SD Memory Card Socket (U44)
An SD card socket (U44) for SD memory card installation is located next to the UART connector of the
board.
Figure 25
shows how to install a compact flash card.

LCD Connectors (J21, J22)
Two headers (J21, J22) are provided for LCD connections. They use the MPC8313E GPIO interface. Both
headers carry the same set of GPIO signal pins, but they are different physically. J21 is single row of
1
×
14, and J22 is double row of 2
×
7.
