PCI Controller
Fully compliant with PCI 2.1 specification.
Integrated PCI arbitration interface. Up to 3
masters can connect directly. External PAL
allows for greater than 3 masters.
Translation of PCI cycles to ISA bus.
Translation of ISA master initiated cycle to
PCI.
Support for burst read/write from PCI master.
PCI clock is 1/3 or 1/2 Host clock .
ISA master/slave controller
Generates the ISA clock from either
14.318MHz oscillator clock or PCI clock
Supports programmable extra wait state for
ISA cycles
