Receive Termination Control (RxTSEL):
Upon power up, the receivers are in "High" impedance.
Switching to internal termination can be selected through
the microprocessor interface by programming the appro-
priate channel register. However, to switch control to the
hardware pin, RxTCNTL must be programmed to "1" in the
appropriate global register (0x0FE2). Once control has
been granted to the hardware pin, it must be pulled "High"
to switch to internal termination.
NOTE: Internally pulled "Low" with a 50k
resistor.

Transmit Positive Analog Output (TTIPn):
TTIP is the positive differential output to the line interface. This out-
put pin, along with the corresponding TRING output pin, function as
the Transmit DS1/E1 output signal drivers for the XRT86VX38
device.
The user is expected to connect this signal and the corresponding
TRING output signal to a 1:2 step up transformer for proper opera-
tion.
This output pin will be tri-stated whenever the user sets the “TxON”
input pin or register bit (0xnF02, bit 3) to “0”.
NOTE: This pin should have a series line capacitor of 0.68
F for DC
blocking purposes.
