    Clear to Send (active LOW). These inputs are
    associated with individual UART channels A to D. A
    logic 0 on the CTSn pin indicates the modem or data
    set is ready to accept transmit data from the
    SC16C554B/554DB. Status can be tested by reading
    MSR[4]. This pin only affects the transmit or receive
    operations when auto-CTS function is enabled via
    MCR[5] for hardware flow control operation.

    Data bus (bidirectional). These pins are the 8-bit,

    the controlling CPU. D0 is the least significant bit and
    the first data bit in a transmit or receive serial data
    stream.

    Data Set Ready (active LOW). These inputs are
    associated with individual UART channels, A through
    D. A logic 0 on this pin indicates the modem or data set
    is powered-on and is ready for data exchange with the
    UART. This pin has no effect on the UART’s transmit or
    receive operation.

    Data Terminal Ready (active LOW). These outputs
    are associated with individual UART channels, A
    through D. A logic 0 on this pin indicates that the
    SC16C554B/554DB is powered-on and ready. This pin
    can be controlled via the Modem Control Register.
    Writing a logic 1 to MCR[0] will set the DTRn output to
    logic 0, enabling the modem. This pin will be a logic 1
    after writing a logic 0 to MCR[0], or after a reset. This
    pin has no effect on the UART’s transmit or receive
    operation.

    Interrupt A, B, C, D (active HIGH). This function is
    associated with the 16 mode only. These pins provide
    individual channel interrupts INTA to INTD.
    INTA to INTD are enabled when MCR[3] is set to a
    logic 1, interrupts are enabled in the Interrupt Enable
    Register (IER), and when an interrupt condition exists.
    Interrupt conditions include: receiver errors, available
    receiver buffer data, transmit buffer empty, or when a
    modem status flag is detected. When the 68 mode is
    selected, the functions of these pins are re-assigned.
    68 mode functions are described under their respective
    name/pin headings.
