The memory bank select register (BANK) is used to select a memory bank to be used.
BANK can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears BANK to 00H.
Caution Be sure to change the value of the BANK register in the common area (0000H to 7FFFH).

BANK
If the value of the BANK register is changed in the bank area (8000H to BFFFH), an inadvertent
program loop occurs in the CPU. Therefore, never change the value of the BANK register in the bank
area.
