PCI Local Bus Addresses
Figure describes the PCI CD/CDa interface registers in detail. The addresses listed are offsets from
the gate array boot ROM base addresses. This base address is initialized by the host operating system at
boot time.
Note
The addresses 0x80 and 0x84 are used by the pciload utility to update the gate array. User
applications must not modify use these registers. Results of running pciload do not take effect
until after the board has been turned off and then on again.
