Access Detail(1)
1. The 3-cycle loop in parentheses expands to five cycles for separators when weighting is enabled. The loop is executed
once for each element in the rule list. When an interrupt occurs, there is a 2-cycle exit sequence, a 4-cycle re-entry
sequence, then execution resumes with a prefetch of the last antecedent or consequent being processed at the time of the
interrupt.
