*Notes:
1. For parts compliant to the 3.3V signaling environment:
Maximum times are evaluated with the following load circuits, for high-g-
oing and low-going edges respectively.
2. REQ and GNT_ are point-to-point signals, and have different output
valid delay and input setup times than do bused signals. GNT_ has a
setup of 10; REQ has a setup of 12. All other signals are bused.
3. RST_ is asserted and deasserted asynchronously with respect to CLK.
4. All output drivers must be asynchronously floated when RST_ is active.
