Receive External Resistor Control Pins
Hardware mode Only
These pins are used in the Receive Internal Impedance mode for unique applica-
tions where an accurate resistor can be used to achieve optimal return loss. When
RxRES[1:0] are used, the LIU automatically sets the internal impedance to match
the line build out. For example: if 240
is selected, the LIU chooses an internal
impedance such that the parallel combination equals the impedance chosen by
TERSEL[1:0].
"00" = No External Fixed Resistor
"01" = 240
"10" = 210
"11" = 150

:
These pins are internally pulled “Low” with a 50k
resistor. This feature is
available in Host mode by programming the appropriate channel register.

I
Receive Clock Edge
Hardware Mode
This pin is used to select which edge of the recovered clock is used to update data to
the receiver on the RPOS/RNEG outputs. By default, data is updated on the risinge
edge. To udpdate data on the falling edge, this pin must be pulled "High".
Host Mode
μ
PTS[2:1] pins are used to select the type of microprocessor to be used for Host
communication.
"00" = 8051 Intel Asynchronous
"01" = 68K Motorola Asynchronous
"11" = MPC8xx Power PC Synchronous
