Delay Loops in 8085 Loop is used in 8085 for repeating the execution of a set of instructions. Loops are also used in generating the delays in 8085. The Loop is implemented by using the DCR and some conditional JMP instructions. A simple Loop is shown below MVI A, 00 MVI C, 05 Again:          DCR C            ADD C JNZ again This program make use of a add instruction inside a loop which executed five times. At the end of the loop addition of five numbers 0 to 5 is obtained which is 15. We can also use loop to generate delay time for some applications. The delay is actually the total ‘T’ states times the clock period. i.e. TL =
