Receive External Resistor Control Pins - Hardware mode
Receive External Resistor Control Pin 1:
Receive External Resistor Control Pin 0:
These pins determine the value of the external Receive fixed resistor according to the
following table:
NOTE: These pins are internally pulled “Low” with a 50k
Ω resistor.

I
Receive Clock Edge - Hardware mode
Set this pin “High” to sample RPOS_N/RNEG_n on the falling edge of RCLK_n. With
this pin tied “Low”, output data are updated on the rising edge of RCLK_n.
Microprocessor Type Select Input pin 1 - Host mode
This pin along with PTS2 (pin 128) is used to select the microprocessor type.
NOTE: This pin is internally pulled “Low” with a 50k
Ω resistor.
