Transmit Clock Edge - Hardware Mode
With this pin set to a "High", transmit input data of all channels are sampled at
the rising edge of TCLK_n. With this pin tied "Low", input data are sampled at
the falling edge of TCLK_n.
Microprocessor Type Select Input pin 2 - Host Mode
This pin should be tied to GND. µPTS1(pin 106) selects the microprocessor
type.

Transmitter Tip Output for Channel _n:
This output pin, along with the corresponding TRING_n output pin, functions
as the Transmit DS1/E1 Output signal drivers for the XRT83L34 device.
The user is expected to connect this signal and the corresponding TRING_n
output signal to a "1:2.45" step-up transformer.
Whenever the Transmit Section of (a given channel within the XRT83L34
device) generates and transmits a "positive-polarity" pulse (onto the line), this
output pin will be pulsed to a "higher-voltage" than its corresponding TRING_n
output pins.
Conversely, whenever the Transmit Section (of a given channel within the
XRT83L34 device) generates and transmits a "negative-polarity" pulse (onto
the line), then this output pin will be pulsed to a "lower-voltage" than that of the
TRING_n output pin.
