3) Selectable Master registers (SM) - these registers can be accessed by either

the PCI Host or the microprocessor at any given moment as configured by

input, MPENB. Input MPENB must be set when the device is powered up.

When these registers are accessed by the PCI Host, it must be on double

word boundaries.

The register map for the PCI Host interface and the microprocessor interface is

shown below. The first column indicates the type of register as detailed above. The

second column contains the microprocessor addresses of the register if the register

can be accessed using the interface. The third column contains the PCI interface

DWORD address of the register if the register can be accessed using the interface.

The PCI index address must be combined with a base address to form the PCI

Interface address. The base address can be found in the LASAR-155 Memory

Base Address register in the PCI Configuration memory space. The fourth column

contains the name of the register.
