Byte 0
This bit always reads back ‘0’, indicating that this base address register defines a PCI memory
space.
These bits indicate that the controller can be located anywhere in the 32-bit address space.
This bit indicates that the Controller registers are not prefetchable.
This field specifies the memory-mapped register space of the CL-PD6833. The Operation
registers can be accessed through this window only after these bits are set to a non-zero value.
