Transmit STS-3/STM-1 Telecom Bus - Channel 3 - Input Data Bus
Pin Number 1/REQ_3 (General Purpose) output Pin:
The function of this pin depends upon whether or not theSTS-3/STM-
1 Telecom Bus Interface, associated with Channel 3 is enabled.
If STS-3/STM-1 Telecom Bus (Channel 3) has been enabled -
STS-3/STM-1 Transmit Telecom Bus - Input Data Bus Pin Num-
ber 1:
This input pin along with STS3TxA_D_3[7:2] and STS3TxA_D_3_0
function as the STS-3/STM-1 Transmit (Add) Telecom Bus - Input
Data Bus for Channel 3. The STS-3/STM-1 Telecom Bus interface
will sample and latch this pin upon the falling edge of
STS3TxA_CLK_3.
If STS-3/STM-1 Telecom Bus (Channel 3) is disabled - REQ_3
(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 appropri-
ate value into Bit 5 (REQB) within the Line Interface Drive Register
associated with Channel 3 (Indirect Address = 0x4E, 0x80), (Direct
Address = 0x4F80).

because one possible application is to tie this output pin to
an REQB (Receive Equalizer By-Pass) or REQEN (Receive
Equalizer Enable) 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 REQ_3
