Outline of operation
● This instruction searches for the string data specified by [S1] in the string table starting from
[S2].
● For [p], specify the relative position (by byte) in the string table where the search starts.
● For the search result, the number of same character data is stored in the device whose
address is specified by [D], and the relative position (by byte) of the first match is stored in [D
+1].
