F10_BKMV_OFFSET
Description
This instruction is a modification of the F10_BKMV (see page 819) generated by the compiler.
The data block specified by the 16-bit starting area specified by s1_Start and 16-bit ending area
specified by s2_End are copied to the block starting from the 16-bit area specified by the offset
d_Offset from s1_Start if the trigger EN is in the ON-state.
Whenever s1_Start and s2_End are in the same data area:
d_Offset = 0: data will be recopied to the same data area.
