Transmit Line Clock Output
TLCLK: This signal is available when the transmit line interface pins are enabled

and TNEG signals, but can also be used as the reference for the TSOFI, TSER, and
TSOFO / TDEN signals.
This output signal can be inverted.

Transmit Positive AMI / Data Output
TPOS: When the port line interface is configured for B3ZS, HDB3 or AMI mode and
the transmit line interface pins are enabled
indicates that a positive pulse should be transmitted on the line. The signal is updated
on the positive clock edge of the referenced clock pin if the clock pin signal is not
inverted, otherwise it is updated on the falling edge of the clock. The signal is typically
referenced to the TLCLK line clock output pins, but it can be referenced to the
TCLKO, TCLKI, RLCLK or RCLKO pins. This output signal can be disabled when the
TX LIU is enabled.
This output signal can be inverted.
TDAT: When the port line interface is configured for UNI mode and the transmit line
interface pins are enabled
output on this pin. The signal is updated on the positive clock edge of the referenced
clock pin if the clock pin signal is not inverted, otherwise it is updated on the falling
edge of the clock. The signal is typically referenced to the TLCLK line clock output
pins, but it can be referenced to the TCLKO, TCLKI, RLCLK or RCLKO pins
This output signal can be inverted.
