Table 62 provides the timing parameters for 3.3V PCI signaling environments
applicable to the PACE, and Figure 13 shows the timing reference points. The
timing parameters apply to the other timing diagrams, but are not illustrated. The
PACE conforms to revision 2.2 of the PCI Local Bus specification. The timing
parameters are provided here for ease of reference only.

Figure 13 illustrates a PCI read from the PACE’s configuration space. The
PACE only responds to Type Zero configuration access: AD[1:0] must be 00
during the command phase. The PACE will drive a full Dword on the AD lines
independent of which byte enables are asserted during the configuration read.
