    P40
    H
    (STBC)
    General-purpose I/O port
    When UART0 is operating, the data at the pin is used as the
    serial input (SIN0).
    Can be set as an open-drain output port (OD40 = “1”) by the
    open-drain control register (ODR4).
    The setting does not apply for ports set as inputs (D40 = “0”:
    invalid at the input setting).
    SIN0
    Functions as the UART0 serial input (SIN0).

    P41
    G
    (STBC)
    General-purpose I/O port
    Functions as the SOT0 pin if the SOE bit in the UMC register is
    “1”.
    Can be set as an open-drain output port (OD41 = “1”) by the
    open-drain control register (ODR4).
    The setting does not apply for ports set as inputs (D41 = “0”:
    invalid at the input setting).
    SOT0
    Functions as the UART0 serial data output pin (SOT0).
