5.4.3 16-bit data dissociation
The result from AND or Or with 16-bit data is divided into one pair of 8-bit data when this
function is used.

When D No. (Dn) storing 16-bit data to be dissociated is entered in D110 and D No. in
which upper 8-bit data is placed after the dissociation is entered in D111, and F111 is exe-
cuted, the dissociated two data are placed in Dm (D111) and Dn (DIIO).
(2) The data to be dissociated may be binary 16-bit data or BCD 4-digit data.

Ex.:
Content (BCD 4-digit data) of D5 are divided into two-digit BCD data, and placed in D5
and D20 separately.
