To use the atom PPS driver 22, you need to mark at least one other refclock or network server "prefer". So typically, you'd configure either 127.127.20.0 with flag1 1 to enable NMEA+PPS using a single driver, or you'd configure 127.127.20.0 prefer with flag1 0 (default) and appropriate time2 alongside 127.127.22.0.
