    *1: If booster is selected, EC2 and TO2 will be redirected to P03/INT23 and P04/INT24 respectively.
    Segment output of P14/SEG27/AN0 to P17/SEG30/AN3 will be disabled.
    *2: For product other than MB89P485, C pin is NC pin.
    *3: If booster is selected, it serves as V0. If booster is not selected, it serves as SEG0.
    *4: P20 to P23 are CMOS I/O ports. P24 to P27 are N-ch open-drain I/O ports. P57 is input-only port.
