1. Logical instructions that affect a bit are in Table 27.
2. A shaded cell denotes an instruction in 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. If this instruction addresses an I/O Port (Px, x = 0-3), add 2 to the number of states. Add 3 if it addresses a Peripheral SFR.
5. If this instruction addresses external memory location, add N+2 to the number of states (N: number of wait states).
6. If this instruction addresses external memory location, add 2(N+2) to the number of states (N: number of wait states).
