-       Register Use
-       r3:source address and return length of string
-       r4:byte counter
-
-       Implementation description
-       Load 2 words at a time and count bytes, if we find null we subtract one from
-       the count and return the count value. We need to subtract one because
-       we don't count the null character as a byte. */
