    Timer drivers should select this flag if they are capable of
    supporting tickless operation.  That is, a call to
    sys_clock_set_timeout() with a number of ticks greater than
    one should be expected not to produce a call to
    sys_clock_announce() (really, not to produce an interrupt at
    all) until the specified expiration.

Defaults

No defaults. Implicitly defaults to ``n``.
