ORG-identifier 81h-FFh
To transfer data blocks of the number range 256 ... 32768 you may use the
ORG identifier 81h-FFh.
For the setting of a DB No. >255 needs a length of one word, the DBNO
new
is assembled from the content of the ORG identifier and the DBNO.
DBNO
new
is created as word as follows:
DBNO
new
High-Byte Low-Byte
0 X X X X X X X X X X X X X X X
ORG-identifier (0XXXXXXX) DBNO (XXXXXXXX)
If the highest Bit of the ORG identifier is set, the Low-Byte of DBNO
new
is
defined via DBNO and the High-Byte of DBNO
new
via ORG identifier, where
the highest Bit of the ORG-identifier is eliminated.
The following formula illustrates this:
DBNO
new
=256 x (ORG-identifier AND 7Fh) + DBNO
