+Description:
+		Use a counter for counting cycles. This is used to repurpose/dedicate
+		any of the counters in the block to counting cycles. Each counter is
+		represented by a bit (bit 0 for counter0, bit1 for counter1 and so on)
+		and setting the corresponding bit will reserve that specific counter
+		for counting cycles and override the event<N> setting.
