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.

Most MOV variations that target memory perform a read cycle on the destination, which will reset T2OUT.^[3]
