Equalizer Control Input 4 - Hardware mode
This pin together with pins EQC[3:0] is used to control the transmit pulse shaping,
transmit line build-out (LBO) and receive monitoring while operating at one of either the
T1, E1 or J1 clock rates/modes.

Transmit Equalizer Control bits.

NOTES:
1.
In Hardware mode all transmit channels share the same pulse setting
controls function.
2.
All channels of an XRT83L38 must operate at the same clock rate, either the
T1, E1 or J1 modes.
In Host mode, these pins perform various microprocessor functions.
NOTE: Internally pulled “Low” with a 50k
Ω resistor.

Receiver Termination Select
In Hardware mode, when this pin is “Low” the receive line termination is determined
only by an external resistor. When “High”, the receive termination is realized by the
internal resistor or the combination of internal and external resistors. These conditions
are described in the table below.
NOTE: In Hardware mode all channels share the same RXTSEL control function.
In Host mode, the RXTSEL_n bits in the channel control registers determine if the
receiver termination is external or internal. However, the function of RXTSEL can be
transferred to the Hardware pin by setting the TERCNTL bit (bit 6) to “1” in the register
address hex 0x82.
NOTE: This pin is internally pulled “Low” with a 50k
Ω resistor.

Transmit Termination Select - Hardware Mode
When this pin is “Low” the transmit line termination is determined only by an external
resistor. When “High”, the transmit termination is realized only by the internal resistor.
NOTES:
1.
This pin is internally pulled “Low” with a 50k
Ω resistor.
2.
In Hardware mode all channels share the same TXTSEL control function.
