*
- * To avoid discarding a valid timestamp that just
- * happened at the "wrong" time, we need to confirm

- * assuming that no two timestamps in sequence have
- * the same nanosecond value.
+ * Workaround: Read TXSTMPH_0 here to enable future interrupts.
+ * However, this read clears TXTT_0. If a timestamp arrives in
+ * register 0 after checking TXTT_0 but before this read, it
+ * would be lost.
*
- * So, we read the "low" register, read the "high"
- * register (to latch a new timestamp) and read the
- * "low" register again, if "old" and "new" versions
- * of the "low" register are different, a valid
- * timestamp was captured, we can read the "high"
- * register again.
+ * To detect this race: We saved a baseline read of TXSTMPL_0
+ * before TXTT_0 check. After performing the workaround read of
+ * TXSTMPH_0, we read TXSTMPL_0 again. Since consecutive
+ * timestamps never share the same nanosecond value, a change
+ * between the baseline and new TXSTMPL_0 indicates a timestamp
+ * arrived during the race window. If so, read the complete
