These pins are active only when the corresponding TxON bits are set.
Table below shows the status of the transmitter based on theTxON bit and TxON
pin settings.

These pins will be active and can control the TTIP and TRING outputs
only when the TxON_n bits in the channel register are set .
When Transmitters are turned off the TTIP and TRING outputs are Tri-
stated.
These pins are internally pulled up.

The frequency accuracy of this input clock must be of nominal bit rate ± 20 ppm.
The duty cycle can be 30%-70%.
By default, input data is sampled on the falling edge of TxCLK.
