Table 21. Summary of Increment and Decrement 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 2 to the number of states. Add 3 if it addresses a Peripheral SFR.
Table 22. Summary of Compare Instructions
Notes:
1. 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.
2. If this instruction addresses external memory location, add N+2 to the number of states (N: number of wait states).
3. If this instruction addresses external memory location, add 2(N+2) to the number of states (N: number of wait states).
