    Description
    Main clock
    input
    XIN
    I
    I/O pins for the main clock generation circuit. Connect a ceramic
    resonator or crystal oscillator between XIN and XOUT. To use the
    external clock, input the clock from XIN and leave XOUT open.
    Main clock
    output
    XOUT
    O
    Sub clock
    input
    XCIN
    I
    I/O pins for a sub clock oscillation circuit. Connect a crystal oscillator
    between XCIN and XCOUT. To use the external clock, input the clock
    from XCIN and leave XCOUT open.
    Sub clock
    output
    XCOUT
    O
    Clock output
    CLKOUT
    O
    The clock of the same cycle as fC, f8, or f32 is outputted.
    INT interrupt
    input
    INT0 to INT4
    I
    Input pins for the INT interrupt.
    NMI interrupt
    input
    NMI
    I
    Input pin for the NMI interrupt.
    Key input
    interrupt input
    KI0 to KI3
    I
    Input pins for the key input interrupt.
    Timer A
    TA0OUT to
    TA2OUT
    I/O
    These are timer A0 to timer A2 I/O pins. (however, the output of
    TA0OUT for the N-channel open drain output.)
    TA0IN to TA2IN
    I
    These are timer A0 to timer A2 input pins.
    Timer B
    TB0IN to TB2IN
    I
    These are timer B0 to timer B2 input pins.
    Serial
    interface
    CTS0 to CTS2
    I
    These are send control input pins.
    RTS0 to RTS2
    O
    These are receive control output pins.
    CLK0 to CLK2
    I/O
    These are transfer clock I/O pins.
    RXD0 to RXD2
    I
    These are serial data input pins.
    TXD0 to TXD2
    O
    These are serial data output pins. (however, TXD2 for the N-channel
    open drain output.)
    CLKS1
    O
    This is output pin for transfer clock output from multiple pins function.
    I2C mode
    SDA0 to SDA2
    I/O
    These are serial data I/O pins. (however, SDA2 for the N-channel
    open drain output.)
    SCL0 to SCL2
    I/O
    These are transfer clock I/O pins. (however, SCL2 for the N-channel
    open drain output.)
    Reference
    voltage input
    VREF
    I
    Applies the reference voltage for the A/D converter.
    A/D converter
    AN0 to AN7,
    AN0_0 to AN0_7
    I
    Analog input pins for the A/D converter.
    ADTRG
    I
    This is an A/D trigger input pin.
    ANEX0
    I/O
    This is the extended analog input pin for the A/D converter, and is the
    output in external op-amp connection mode.
    ANEX1
    I
    This is the extended analog input pin for the A/D converter.
    I/O port
    P0_0 to P0_7,
    P1_0 to P1_7,
    P2_0 to P2_7,
    P3_0 to P3_7,

    P9_0 to P9_7,
    P10_0 to P10_7
    I/O
    8-bit I/O ports in CMOS, having a direction register to select an input
    or output.
    Each pin is set as an input port or output port. An input port can be set
    for a pull-up or for no pull-up in 4-bit unit by program. (however, P7_0
    and P7_1 for the N-channel open drain output.)
    P8_0 to P8_4,
    P8_6, P8_7
    I/O
    I/O ports having equivalent functions to P0.
    Input port
    P8_5
    I
    Input pin for the NMI interrupt. Pin states can be read by the P8_5 bit
    in the P8 register.
