-	 * Weird behavior: the X axis will be read instead of the temperature registers if you use a pointer to a packed struct...not sure why.

+	 * Silicon Bug: the X axis will be read instead of the temperature registers if you do a sequential read through XYZ.
+	 * The temperature registers must be addressed directly.
