conditional jump instructions in 8085
What are conditional jump instructions in 8085?
The complete list of conditional jump instructions in 8085 is described in the following table. Jump to the specified location unconditionally. The Call and Return instructions in 8085 are associated with the subroutine technique.
What is JNZ A16 in 8085 instruction set?
In 8085 Instruction set, we are having one mnemonic JNZ a16, which stands for “Jump if Not Zero” and “a16” stands for any 16-bit address. This instruction is used to jump to the address a16 as provided in the instruction. But as it is a conditional jump so it will happen if and only if the present zero flag value is 0.
What happens if a condition is not satisfied in 8085?
The 8085 evaluates the condition while it fetches the second instruction byte. If the specified condition is not satisfied, the 8085 skips over the third instruction byte and immediately fetches the next instruction. Skipping the unnecessary byte allows for faster execution.
What are unconditional jump instructions?
Unconditional jump instructions allow the programmer to set up continuous loops. Jump to the specified location unconditionally. Conditional jump instructions allow the microprocessor to make decisions based on certain conditions indicated by various flags.
