Set the number of bytes of source data from words S+1 on. For
example, set S to 000A hex if there are 5 words of data (S+1 to
S+5). Do not include the 2 bytes in word S itself. Include the
leftmost bytes of S+1 to S+5, which contain 00.
Also, include the number of bytes of Service Data starting at S+6.
(If the first or last word contains just one byte of data, do not count
the empty byte in that word.)
