Data Bus Pin Number 0/TxLEV_1 (General Purpose) Out-
put Pin:
The function of this output pin depends upon whether or not
theSTS-3/STM-1 Telecom Bus Interface, associated with
Channel 1 is enabled.
If STS-3/STM-1 Telecom Bus (Channel 1) has been enabled
- STS-3/STM-1 Receive Telecom Bus - Output Data bus Pin
Number 0: STSRxD_D_1_0:
This output pin along with STS3RxD_D_1[7:1] function as the
STS-3/STM-1 Receive (Drop) Telecom Bus - Output Data Bus
for Channel 1. The STS-3/STM-1 Telecom Bus Interface will
update the data via this output upon the rising edge of
STS3RxD_CLK_1.
N
If STS-3/STM-1 Telecom Bus (Channel 1) is disabled -
TXLEV_1 (General Purpose) output Pin:
This output pin can be used as a general purpose output pin.
The state of this output pin can be controlled by writing the
appropriate value into Bit 2 (TxLEV) within the Line Interface
Drive Register associated with Channel 1 (Indirect Address =
0x2E, 0x80), (Direct Address = 0x2F80).

OTE
: This input pin functions as the LSB (Least Significant
:
Bit) of the Receive (Drop) Telecom Bus for Channel 1.
TxLEV_1 because one possible application is to tie this
output pin to a TxLEV (Transmit Line Build-Out
Disable) input pin from one of Exar's XRT73L0X/
XRT75L0X DS3/E3/STS-1 LIU devices. However, this
output pin, and the corresponding register bit can be
used for any purpose.
For Product Legacy purposes, this pin is called
