• Bank switching is begun 0.2 seconds after the input state changes.
• At most it takes about 100ms to switch banks.
• During bank switching, the BUSY output becomes ON.
• If the bank mode is set to [JUDGE], the bank cannot be switched at the external signal input because the number of
banks increases to 32.
