Connector X2 Signal Description

ISA Bus
The implementation of this subsystem complies with the ETX® Specification. Implementation information is provided in
the ETX® Design Guide. Refer to the documentation for additional information.
Restrictions:
Memory Transfer: According to the used LPC 2 ISA solution only memory transfer in the Firmware HUB memory range and
with Firmware HUB commands is possible. The Firmware HUB range is from FED4:0000 to FED4:0FFF
I/O Transfer: Only two generic decoding ranges are available which can be selected in the BIOS setup with a maximum size
of 256 Byte. This works of course only, when there are no other devices connected to that I/O ports in that range. It can
be that there is only one decoding range available, when there are the COM and/or parallel ports of an external SuperI/O
controller used.
Signal level: The signal level of the used Fintec controller is 3,3V, 5V tolerant. To achieve the 5V level, most of the signals
are pulled up to 5V.

Flat-Panel Interfaces
ETX®-CD modules can implement an LVDS flat-panel interface called JUMPtec Intelligent LVDS Interface (JILI). These
modules do not implement a parallel digital flat-panel interface called JUMPtec Intelligent Digital Interface (JIDI).
