    Bus collision detection (SIO1)
    SIO1 can detect a bus collision by setting UART1 bus collision de-
    tection interrupt enable bit.
    When transmission is started in the clock synchronous or asyn-
    chronous (UART) serial I/O mode, the transmit pin TxD1 is
    compared with the receive pin RxD1 in synchronization with rising
    edge of transmit shift clock. If they do not coincide with each other,
    a bus collision detection interrupt request occurs.
    When a transmit data collision is detected between LSB and MSB
    of transmit data in the clock synchronous serial I/O mode or be-
    tween the start bit and stop bit of transmit data in UART mode, a
    bus collision detection can be performed by both the internal clock
    and the external clock.
    A block diagram is shown in Fig. 54.
    A timing diagram is shown in Fig. 55.
    Note: Bus collision detection can be used when SIO1 is operating
    at full-duplex communication. When SIO1 is operating at
    half-duplex communication, set bus collision detection inter-
    rupt to be disabled.
