Signal Groups
The signal description includes the type of buffer used for the particular signal.
AGTL+
Open Drain AGTL+ interface signal. Refer to the AGTL+ I/O Specification for complete
details. The Intel 845MP/845MZ Chipset MCH-M integrates most AGTL+ termination
resistors.
AGP
AGP interface signals. These signals are compatible with AGP 2.0 1.5 V Signaling
Environment DC and AC Specifications. The buffers are not 3.3 V tolerant.
HI CMOS
Hub Interface 1.8 V CMOS buffers.
DDR CMOS DDR System memory 2.5 V CMOS buffers.
