The Move Out Indirect (MVO@) instruction copies the value in the specified source register to the address contained by the specified address register. Note that if the address register specified is R4-R7 (the auto-incrementing registers), then the value in the address register will be incremented by one after the value in the source register has been stored at the designated address.
