Copying source devices to multiple destinations (FMOV)

The FMOV (Fill MOVe) instruction copies the contents of a word device or a constant to multi-
ple consecutive word devices. It is generally used to delete data tables and to set data regis-
tered to a predefined starting value.

The following example writes the value "0" to 7 elements:
– Data source: K0 (constant)
– Data destination: D10
– Number of elements to be written in the destination range: 7

Here too, FMOV has a pulse-triggered version, FMOVP (see section 6.2.1 for details on
