1.
This PCI interface conforms to the PCI Local Bus Specification, Rev 2.2.
2.
PCICLK must be equal to or less than two times ICLK (PCICLK <= 2(ICLK)) with a maximum PCICLK of 66MHz.
3.
The values for this symbol were determined by calculation, not by testing.
4.
PCIRSTN is an output in host mode and an input in satellite mode.
5.
To meet the PCI delay specification from reset asserted to outputs floating, the PCI reset should be logically combined with the COLDRSTN input, instead of input on PCIRSTN.
6.
PCISERRN and PCIMUINTN use open collector I/O types.
