Memory Map Example
The default base address for the KS8695P system conguration registers is 0x03ff0000. After power up, the user is free to re-
map the memory for their specic application. The following is an example of the memory space remapped for operation.

Register Description
The KS8695P system conguration registers (SCRs) are located in a block of 64KB in the host memory address space.
After power up and initialization, the user can remap the SCRs to a desired offset. The SCRs are 32 bits wide. They are 32
bit word-aligned and must be accessed using word instructions.
The AHB-PCI bridge conguration registers are also included in the SCRs. A subset of the AHB-PCI bridge conguration
registers is also accessible to an external PCI host when the KS8695P is congured in PCI guest mode. Refer to the detailed
Register Description document for additional information, including bit denitions. If you don’t have this document, contact
your local Micrel Field Application Engineer or salesperson.
