Allows for 1 MB bounded PCI bus address space to be blocked off as
MUSYCC space. MUSYCC responds as a PCI slave with DEVSEL* to all bus
cycles whose address bits 31:20 match the value of bits 31:20 of this
register, and whose upper address bits are non-zero, and memory space is
enabled in the Function 0 Register 1, memory space bit field.
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 MUSYCC function
can be assigned.
MUSYCC memory space is not prefetchable.
MUSYCC can be located anywhere in 32-bit address space.
This base register is a memory space base register, as opposed to I/O
mapped.
Reads to addresses within this space that are not implemented will
