In the case of constants
The right figure shows an example of the indexing
operation in which the transfer source in the MOV
instruction is indexed with the index register V6.
Transfer K0 or K20 to the index register V6 in
advance.
When X005 is set to ON and if V6 is "0", K6 (=
K(6+0))is transferred to D10.
When X005 is set to ON and if V6 is "20", K26 (=
K(6+20))is transferred to D10.
