7.2 Size and Execution Time for Instruction Families
Table 20. Summary of Add and Subtract Instructions
Notes:
1. A shaded cell denotes an instruction in the C51 Architecture.
2. 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.
3. If this instruction addresses external memory location, add N+2 to the number of states (N: number of wait states).
4. If this instruction addresses external memory location, add 2(N+2) to the number of states (N: number of wait states).
