mov

The move instructions copy data from one register or memory location to another.

1. no identity movs (ddd = rrr), no mov [pi], acc (ddd = 110 and rrr = 111), and no mov acc, [pi] (ddd = 111 and rrr = 110)
2. no identity movs (vv = ww)
3. if the destination register is acc
4. if the destination is [pi] and without prefix_a16
5. if the destination is [pi] and with prefix_a16 (the cycle of prefix_a16 itself is not included)
6. if the source is [pi] and without prefix_a16
7. if the source is [pi] and with prefix_a16
8. with prefix_a16
9. if $(\mathit{reg16} + \mathit{sext}(\mathit{imm8}))[8:15] \neq \mathit{reg16}[8:15]$
