 * Notes:
 * TIM has a counter that causes a periodic tick every 1024 cycles. This counter is shared by all
 * rings. (Each tick causes the HW to decrement the time offset (i.e. COUNT) for all enabled rings.)
 * When ENA_TIM==0, the HW stops this shared periodic counter, so there are no more ticks, and there
 * are no more new bucket traversals (for any ring).
 *
 * If ENA_TIM transitions 1->0, TIM will no longer create new bucket traversals, but there may
 * have been previous ones. If there are ring bucket traversals that were already pending but
 * not currently active (i.e. bucket traversals that need to be done by the HW, but haven't been yet)
 * during this ENA_TIM 1->0 transition, then these bucket traversals will remain pending until
 * ENA_TIM is later set to one. Bucket traversals that were already in progress will complete
 * after the 1->0 ENA_TIM transition, though.
