FSB Signal Groups
The FSB signals have been combined into groups by buffer type in the following 
sections. In this document, the term “AGTL+ Input” refers to the AGTL+ input group as 
well as the AGTL+ I/O group when receiving. Similarly, “AGTL+ Output” refers to the 
AGTL+ output group as well as the AGTL+ I/O group when driving. 
With the implementation of a source-synchronous data bus, two sets of timing 
parameters are specified. One set is for common clock signals, which are dependent 
upon the rising edge of BCLK0 (ADS#, HIT#, HITM#, etc.), and the second set is for 
the source-synchronous signals which are relative to their respective strobe lines (data 
and address) as well as the rising edge of BCLK0. Asychronous signals are still present 
(A20M#, IGNNE#, etc.) and can become active at any time during the clock cycle. 
 identifies which signals are common clock, source synchronous, and 
asynchronous.
