Summary of Bit 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 an I/O Port (Px, x = 0-3), add 2 to the number of states.

Add 3 if it addresses a Peripheral SFR.
