Electrical Specifications
With the implementation of a source synchronous data bus comes the need to specify two sets of
timing parameters. 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. Table 2-3 identifies which signals are common clock, source
synchronous, and asynchronous.
NOTES:
1. Refer to Section 4.2 for signal descriptions.
2. EDRDY# and PC_REQ# are not features of the Celeron D processor in the 775-land package. They are
included here for future processor compatibility.
3. The value of these signals during the active-to-inactive edge of RESET# defines the processor configuration
options. See Section 6.1 for details.
4. PC_REQ# is driven by the processor as Common Clock (1X); however, it must be received at the chipset as
Source Synchronous and associated with ADSTB0#.
5. In processor systems where there is no debug port implemented on the system board, these signals are used
to support a debug port interposer. In systems with the debug port implemented on the system board, these
signals are no connects.
