Static ZTIMER_USEC_BASE

pub unsafe static ZTIMER_USEC_BASE: *mut ztimer_clock_t

@brief Base ztimer for the microsecond clock (ZTIMER_USEC)

This ztimer will reference the counter device object at the end of the chain of ztimer_clock_t for ZTIMER_USEC.

If the base counter device object’s frequency (CONFIG_ZTIMER_USEC_BASE_FREQ) is not 1MHz then ZTIMER_USEC will be converted on top of this one. Otherwise they will reference the same ztimer_clock.

To avoid chained conversions its better to base new ztimer_clock on top of ZTIMER_USEC_BASE running at CONFIG_ZTIMER_USEC_BASE_FREQ.
