MOV is an SPC700 instruction that moves a value. There are a large number of variations for this instruction, and they are divided into three groups:
- In Group 1, MOV moves values from ARAM to registers.
- In Group 2, MOV moves values from registers to ARAM.
- In Group 3, MOV moves values from registers to registers or from ARAM to ARAM.
