3.7 Selecting Memory Bank ( PD78F0376, 78F0376D, 78F0386, AND 78F0386D ONLY)
addressed. Therefore, to access a memory bank different from the one currently selected, that memory bank must be
selected by using the BANK register.
the memory bank, branch an instruction to the common area (0000H to 7FFFH) and change the value of the BANK
register in that area.
3.7.1 Referencing values between memory banks
change the setting of the BANK register there, and then reference a value.
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
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),
2. Branching and accessing cannot be directly executed between different memory banks.
3. Allocate interrupt servicing in the common area.
4. An instruction that extends from 7FFFH to 8000H can only be executed in memory bank 0.
