This example is a system consisting of the MCU, a single 27C512-type memory device as in the previ-
ous example, and two 6226-type memory devices as well. This system uses two chip selects and has
two windows. For purposes of explanation, the setup of the first window is identical to the previous ex-
ample. In addition, a second window consisting of 16 banks of 16 Kbytes each uses the second chip
select signal. Window 1 contains 64 Kbytes of expanded memory pages, window 2 contains a total of
256 Kbytes of expanded memory. A total of five expansion address lines are used. Register values par-
ticular to this example are given below the diagram.
