NOTE: These pins are internally pulled “Low” with a 50k resistor.

RCLKE

J16

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

µPTS1

J16

This pin along with µPTS2 (pin 128) is used to select the microprocessor type.
