Have a great day,
It is impossible without hardware changing. The Flash address inputs A23–A25 are not connected to the P4080 local bus addresses A7-A5 directly on the P4080DS. The “address toggle” feature by SW7 is implemented by multistaged XOR gate which adds ngPIXIS signals defined by SW7 and P4080’s A7-A5. See details in section “Local bus” of the P4080 Development System User’s Guide.
