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.

Input 0:
General purpose input, or channel A clear to send active-LOW input (CTSAN). Pin has an
internal V
CC
pull-up device supplying 1 to 4
μ
A of current.
Input 1:
General purpose input, or channel B clear to send active-LOW input (CTSBN). Pin has an
internal V
CC
pull-up device supplying 1 to 4
μ
A of current.
Input 2:
General purpose input, or counter/timer external clock input. Pin has an internal V
CC
pull-up
device supplying 1 to 4
μ
A of current.
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
CC
pull-up device supplying 1 to 4
μ
A 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
CC
pull-up device supplying 1 to 4
μ
A of 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
CC
pull-up device supplying 1 to 4
μ
A 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
