For standard PCI timing, see the PCI Local Bus Specification, Rev. 2.0, especially Chapters 3 and 4.
The HI32 supports these timings for a PCI bus operating at 33 MHz for a DSP clock frequency of 56 MHz and above. The DSP
core operating frequency should be greater than 5/3 of the PCI bus frequency to maintain proper PCI operation.
HGNT has a setup time of 10 ns. HREQ has a setup time of 12 ns.
