2.6 VGPIO 2.6 V buffers used for miscellaneous GPIO signals
CMOS
Host Interface signals that perform multiple transfers per clock cycle may be marked as
either “4X” (for signals that are “quad-pumped”) or 2X (for signals that are “double-
pumped”).
Processor address and data bus signals are logically inverted signals. In other words,
the actual values are inverted of what appears on the processor bus. This must be
taken into account and the addresses and data bus signals must be inverted inside the
MCH host bridge. All processor control signals follow normal convention. A 0 indicates
an active level (low voltage) if the signal is followed by # symbol and a 1 indicates an
active level (high voltage) if the signal has no # suffix.
