technique chains together pins in a serial fashion, with an XOR gate between each pin,
effectively creating a single multi-input XOR gate. By toggling the pins individually or in
combination, the connectivity of the pins are validated at the output pin.
Note:
A test point must be placed on the board for each of these XOR pins.

Signal Pin Descriptions
This section provides I/O signal definitions. The signals are categorized into one of
several blocks:
• IA-32 core
• IMCH
• IICH
• AIOC
• Miscellaneous
• Power
In each block, there are specific functional group interfaces. Table 48-3 summarizes the
signal pin tables that appear throughout this section.
