Procedure for Using Chip Select Base Address Registers
5.3.1
A 16K chip select device is attached to the Local Bus
and a chip select is provided. The base address is
specified to be 24000h. The following figure illustrates
this example.

The following is a complete example of setting the
Chip Select Base Address register with a range of
4000h, a base address of 24000h, and enabled:
