The memory bank selected by the memory bank select register (BANK) is reflected on the bank area and can be
The value of the BANK register must not be changed in the bank area (8000H to BFFFH). Therefore, to change the
Cautions 1. Instructions cannot be fetched between different memory banks.
Values cannot be directly referenced from one memory bank to another.
To access another memory bank from one memory bank, branch once to the common area (0000H to 7FFFH), change
2. Branching and accessing cannot be directly executed between different memory banks. Execute
