- * The following defines are used only if a pulse-per-second (PPS)
- * signal is available and connected via a modem control lead, such as
- * produced by the optional ppsclock feature incorporated in the Sun
- * asynch driver. They establish the design parameters of the frequency-
- * lock loop used to discipline the CPU clock oscillator to the PPS
- * signal.
- *
- * PPS_AVG is the averaging factor for the frequency loop, as well as
- * the time and frequency dispersion.
- *
- * PPS_SHIFT and PPS_SHIFTMAX specify the minimum and maximum
- * calibration intervals, respectively, in seconds as a power of two.
- *
- * PPS_VALID is the maximum interval before the PPS signal is considered
- * invalid and protocol updates used directly instead.
- *
- * MAXGLITCH is the maximum interval before a time offset of more than
- * MAXTIME is believed.
