There are three types of wrs: normal wrs(mark as wrs), wrs with LJD (mark as WRS-LJD), wrs with embedded lowjitter circuits(mark as WRSLJ). lj_loopback_i/o is used to distinguish wrs from WRS-LJD and WRSLJ. lj_osc_freq_i is used to distinguish WRSLJ from WRS-LJD. lj_osc_freq_i=111 means WRSLJ. lj_osc_freq_i=others means WRS-LJD. lj_osc_freq_i[2 downto 0] need to be pulled up
