this pin not connected although it must not be grounded.
is HIGH, “space” is LOW.
Channel B Receive Serial Data Input: The least significant bit is received first. “Mark”
is HIGH, “space” is LOW.
Channel A Transmitter Serial Data Output: The least significant bit is transmitted
first. This output is held in the “mark” condition when the transmitter is disabled, idle or
when operating in local loopback mode. “Mark” is HIGH, “space” is LOW.
Channel B Transmitter Serial Data Output: The least significant bit is transmitted
first. This output is held in the “mark” condition when the transmitter is disabled, idle or
when operating in local loopback mode. “Mark” is HIGH, “space” is LOW.
Output 0: General purpose output or Channel A request to send (RTSAN,
active-LOW). Can be deactivated automatically on receive or transmit.
Output 1: General purpose output or Channel B request to send (RTSBN,
active-LOW). Can be deactivated automatically on receive or transmit.
Output 2: General purpose output or Channel A transmitter 1 or 16 clock output, or
Channel A receiver 1 clock output.
Output 3: General purpose output or open-drain, active-LOW counter/timer interrupt
output or Channel B transmitter 1 clock output, or Channel B receiver 1 clock output.
Output 4: General purpose output or Channel A open-drain, active-LOW,
RxRDYA/FFULLA interrupt output.
Output 5: General purpose output or Channel B open-drain, active-LOW,
RxRDYB/FFULLB interrupt output.
Output 6: General purpose output or Channel A open-drain, active-LOW, TxRDYA
interrupt output.
Output 7: General purpose output or Channel B open-drain, active-LOW, TxRDYB
interrupt output.
Input 0: General purpose input or Channel A clear to send active-LOW input (CTSAN).
Pin has an internal V
Input 1: General purpose input or Channel B clear to send active-LOW input (CTSBN).

V
Input 3: General purpose input or Channel A transmitter external clock input (TxCA).
When the external clock is used by the transmitter, the transmitted data is clocked on
the falling edge of the clock. Pin has an internal V
of current.
Input 4: General purpose input or Channel A receiver external clock input (RxCA).
When the external clock is used by the receiver, the received data is sampled on the
rising edge of the clock. Pin has an internal V
current.
Input 5: General purpose input or Channel B transmitter external clock input (TxCB).
When the external clock is used by the transmitter, the transmitted data is clocked on
the falling edge of the clock. Pin has an internal V
of current.
Input 6: General purpose input or Channel B receiver external clock input (RxCB).
When the external clock is used by the receiver, the received data is sampled on the
rising edge of the clock. Pin has an internal V
current.
Power Supply: +5V supply input.
