Summary of Move Instructions (2/3)
Notes: 1. Instructions that move bits are in Table 27.
2. Move instructions from the C51 Architecture.
3. If this instruction addresses an I/O Port (Px, x = 0-3), add 1 to the number of states.
Add 2 if it addresses a Peripheral SFR.
4. Apply note 3 for each dir8 operand.
