Chapter 9 and Chapter 10 discuss the window mapping technique for PC Card application. Chapter 9
discusses the conventional or standard method for mapping windows. This method is featured in all earlier
versions of Cirrus Logic PC Card products and is also 82365SL–compatible. This method of window
mapping uses seven windows to access the memory and I/O space of the PC Card. The seven windows
consist of two windows dedicated to the I/O space and five windows dedicated to the memory space.
For clarity, labels that describe the window mapping registers are consistent with those in earlier data
sheets.
NOTE: As of this writing, only the Standard Mapping method is used by PC Card software vendors.
Chapter 10 describes another technique for mapping the seven windows, this is called the General
Mapping method. The General Mapping method allows for the flexibility to map any of the seven windows
as either a memory window or an I/O window. Additional flexibility allows mapping from PCI memory
space or PCI I/O space to PC Card memory space or PC Card I/O space. This is shown in Table 9-2.
