This pin transitions "High" if a short circuit condition is detected in the trans-
mit driver, or no transmit output pulse is detected for more than 128 TCLK
cycles.

Twisted Pair Cable Wire Gauge Select
In
Hardware Mode
, connect this pin "High" to select 26 Gauge wire. Connect this pin
“Low” to select 22 and 24 gauge wire.

Transmitter Transformer Ratio Select
In
Hardware Mode
, in external termination mode (TXTSEL = “0”), setting this pin "High"
selects a transformer ratio of 1:2 for the transmitter. A "Low" on this pin sets the transmit-
ter transformer ratio to 1:2.45. In the internal termination mode the transmitter trans-
former ratio is permanently set to 1:2 and the state of this pin is ignored.

OTE
:
Internally pulled "Low" with a 50k

I
Receiver Termination Select
In
Hardware Mode
when this pin is “Low” the receive line termination is determined only
by the external resistor. When “High”, the receive termination is realized by internal
resistors or the combination of internal and external resistors according to RXRES[1:0].
These conditions are described in the following table:
In Host Mode bit 7 in Control Register 1 (01h) determines if the if the receiver termina-
tion is external or internal. The function of RXTSEL can be transferred to the harware pin
by setting TERCNTL bit (bit 4)
