System Memory Window Stop Address A[19:12]
Low order address bits used to determine the stop address of the corresponding system memory
address mapping window. This provides a minimum 4K bytes window for memory address
mapping window.

Wait State bit 1:0.
These bits determine the number of additional wait states for a 16-bit access to the system memory
window. If the PC Card supports the WAIT# signal, wait states will be generated by the PC Card
asserting the WAIT# signal.
00: standard 16-bit cycle ( 3 BUSCLKs per access )
01: 1 additional wait state ( 4 BUSCLKs per access )
10: 2 additional wait states ( 5 BUSCLKs per access )
11: 3 additional wait states ( 6 BUSCLKs per access )

System Memory Window Stop Address A23:20.
High order address bits used to determine the stop address of the corresponding system memory
window.
