Is there a compare jump equal instruction for the 8051?

The 8051 microcontroller does not have a specific "compare jump equal" instruction. Instead, conditional jumps can be achieved using a combination of the CJNE (Compare and Jump if Not Equal) instruction, which checks two registers and jumps if they are not equal, or by using the JZ (Jump if Zero) instruction after a subtraction operation. By setting up the comparison manually and then checking the result, you can effectively implement a compare-and-jump-equal functionality.
