Type:
Read/write
Offset:
CardBus socket address + 840h
Default: 00h
Description: The upper eight bits (upper byte) of a PCI memory address are compared to the contents of this
register when decoding addresses for 16-bit memory windows 0. By programming this register
to a value other than zero, host software can locate 16-bit memory windows in any one of 256
16M-byte regions in the 4G-byte PCI address space. The default register values (00h) locate
16-bit memory windows in the first 16M bytes of address space.
