Advance Information
Allows for 1 MB-bounded PCI bus address space to be blocked off as the
CX28560 space. The CX28560 will respond as a PCI slave with DEVSEL*
to all memory cycles whose address bits 31:20 match the value of bits
31:20 of this register, and those upper address bits are non-zero, and
memory space is enabled in the Register 1, COMMAND bit field.
Reads to addresses within this space that are not implemented read back
0; writes have no effect.
When appended to bits 31:20, these bits specify a 1 MB bound memory
range. 1 MB is the only amount of address space that a CX28560 can be
assigned.
The CX28560 memory space is not prefetchable.
The CX28560 can be located anywhere in 32-bit address space.
This base register is a memory space base register, as opposed to I/O
mapped.
