These bits select the size of memory expansion window 1.
Selects the three most significant bit (MSB) of the base address for memory mapping window 2. Refer
to the table following W1A[15:13].
Always reads zero
Selects the three MSB of the base address for memory mapping window 1. Refer to the following table
for additional information.
Always reads zero

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.
