Hardware Mode: RxClk INVERT
Host Mode: Chip Select:
Function of this pin depends on whether the XRT75L02 is configured to operate
in Hardware mode or Host mode.
In Hardware mode, setting this input pin “High” configures the Receiver Sec-
tion of all channels to invert the RxClk_n output signals and outputs the recov-
ered data via RPOS_n and RNEG_n on the falling edge of RxClk_n.
NOTE: If the XRT75L02 is configured in HOST mode, this pin functions as CS
input pin (please refer to the pin description for Microprocessor
Interface).
