5. Memory Interface
5.1.
Module Signals
If the J800 connector (MiniPCI) is not used, see §5.3, it is possible to interface an external memory
board through the J801 connector. J800 and J801 connectors share the same signals.
These signals are not available via TP on the center of Development Kit. The J801 connector pin out
is listed below.
For further information about the module signals and multiplexing, refer to document [1].
