 Alongside the flash memory, the chip has a shift register connected to pins 2, 4, and 5 on the cartridge. This shift register may control the 7 most significant address bits on the flash. Specifically, it only controls those address bits when the CPU requests an address on the cartridge (A15 HIGH) but in the lower half of cartridge memory (A14 LOW). When an address on the upper half of cartridge memory (A14 HIGH) is requested, the 7 banked address bits are pulled HIGH.
