W1SZ[1:0] —Window 1 Size
These bits select the size of memory expansion window 1.
W2A[15:13] —Window 2 Base Address
Selects the three most significant bit (MSB) of the base address for memory mapping window 2. Refer
to the table following W1A[15:13].
Bit 4 —Not implemented
Always reads zero
W1A[15:13] —Window Base 1 Address
Selects the three MSB of the base address for memory mapping window 1. Refer to the following table
for additional information.
Bit 0 —Not implemented
Always reads zero
NOTE
A special case exists when the bank size is 32 Kbytes and the window base ad-
dress is $4000. The XA14 signal connected to the ADDR14 pin of the memory de-
vice automatically drives an inverted CPU ADDR14 signal onto the XA14 pin when
the window is active. The effect occurs while the CPU address is in the $4000–
$BFFF range, the XA pins and external physical memory range is $0000–$7FFF.
