Using Data Handling Instructions
11–16
The MVM instruction is a word instruction that moves data from a source
location to a destination and allows portions of the destination data to be
masked by a separate word. As long as the rung remains true, the instruction
moves the data each scan.
Entering Parameters

• Source is the address of the data you want to move.
• Mask is the address of the mask through which the instruction moves
data; the mask can be a hex value (constant).
• Destination is the address where the instruction moves the data.
