,/* SRCH */
==== SRCH ====
* To know if a match has been found always look at the status bit. BD will be 1 for a match and 0 for no match. The border x coordinate is always set to something even if there is no match.
* When searching sx and sy are masked before use. If the width is 256, then sx is masked with 255 before use.
