(see the dp83950 data sheet, published by national semiconductor, for details on the ric management bus.) this pin is controlled by a special register, with which you can define the polarity and assertion method (cam match active or not match active) of the pcomp signal. crs_0 f2 i phis carrier sense/carrier sense for 10m. crs is asserted asynchronously with minimum delay from the detection of a non- idle medium in mii mode. crs_10m is asserted when a 10-mbit/s phy has data to transfer. a 10-mbit/s transmission also uses this signal. rx_clk_0 f4 i phis receive clock/receive clock for 10m. rx_clk is a continuous clock signal. its frequency is 25 mhz for 100-mbit/s operation, and 2.5 mhz for 10-mbit/s. rxd[3:0], rx_dv, and rx_err are driven by the phy off the falling edge of rx_clk, and sampled on the rising edge of rx_clk. to receive data, the rxclk_10 m clock comes from the 10mbit/s phy.
