Summary of Conditional Jump Instructions (2/2)
Notes: 1. A shaded cell denotes an instruction in the C51 Architecture.
2. States are given as jump not-taken/taken.
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.
