System Interface Extension
The System Interface Extension is realized using an 80-pin, HIROSE FX8C-80S-SV connector
designated as J23 (P2), and it is used to provide CPU architecture specific system interfaces.
In the case of the EBC2, a CompactFlash interface, a GPIO interface (EB405), and two USB
interfaces are available on the System Interface Extension. The following sections provide fur-
ther information concerning these interfaces.
