4.8.3 LEB CompactFlash* Connector Pinout
The Intel
®
EP80579 Development Board utilizes the Local Expansion Bus interface that
is connected to the CompactFlash connector and runs in True IDE mode. For more
information, refer to CF+ and CompactFlash Specification Revision 4.0, 5/24/06 for the
standard True IDE mode pinout.
4.8.4 HSS Mezzanine Connectors Pinout
The Intel
®
EP80579 Development Board implements three sets of mezzanine
connectors dedicated to HSS devices. There are two primary cards intended for use
with the Intel
®
EP80579 Development Board, an Intel
®
EPAVM80579 Analog Voice
Mezzanine Card (4-port analog voice card) and a Intel
®
EPTEM80579 Quad T1/E1
Mezzanine Card (quad T1/E1 card). The two cards are different with respect to the
offset of the mezzanine connectors: one is offset left, and the other is offset right.
Each mezzanine card has two 120-pin connectors associated with it. The first connector
is referred to as the standard connector and the second connector is referred to as the
expansion connector. The standard connector includes primary and secondary HSS
interfaces, expansion bus, GPIOs and interrupt. The expansion connectors include SSP
signals, extra GPIOs and 8 expansion bus chip select signals.
Table 17 lists the primary and secondary HSS port numbers in each HSS mezzanine
slot.
The Intel
®
EP80579 Development Board utilizes three GPIO pins to provide interrupts
on the HSS mezzanine connectors. Table 18 provides the GPIO pins that are used as
HSS interrupts.
Table 19 shows the pinout of the standard mezzanine connector. Table 20 provides the
pinout of the expansion mezzanine connector.
