Separating 4 Bits From 16-Bit Data - Mitsubishi MELSEC iQ-F FX5 series Programming Manual

Separating 4 bits from 16-bit data

DIS(P)
These instructions store the data equivalent of the (n) nibbles (1-nibble/ 4-bits) of the 16-bit binary data specified by (s) in to
the lower-order 4 bits of (n) number of devices starting from the one specified by (d).

Processing details
• These instructions store the data equivalent of the (n) nibbles (1-nibble/ 4-bits) of the 16-bit binary data specified by (s) in to
the lower-order 4 bits of (n) number of devices starting from the one specified by (d).

(s)
• The higher-order 12 bits of (n) number of devices starting from the one specified by (s) becomes 0.
• When (n) is 0, no processing is performed, and the contents of the (n) number of devices starting from the one specified by
(d) do not change.
