TSC80251G2D
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 an I/O Port (Px, x= 0-3), add 2 to the number of states. Add 3 if it addresses a Peripheral SFR.
Notes:
1. A shaded cell denotes an instruction in the C51 Architecture.
2. States are given as jump not-taken/taken.
3. In internal execution only, add 1 to the number of states of the ‘jump taken’ if the destination address is internal and odd.
