The 16 bit I/O card address space is accessed via 16 bit I/O addresses. The PC Card 16 I/O space is
mapped to the lower 64kByte PCI I/O address space.

To open I/O window, software must provide the PCI1510 with I/O start address, I/O stop address, and
I/O offset.
PC Card16 I/O is accessed only if the address window is enabled and if the I/O address is located
between start and stop address.
For detailed information about window mapping procedure and status / control registers
please refer to the PCI1510 data sheet which is part of the TPMC871-ED Engineering
