WebWhen some time delay is required between two operations, a Time Delay Loop in Microprocessor is used to provide it. Time delay can be generated using a register or a register pair. Initially, a register is loaded with an operand or number and then the number is decremented until it reaches zero. WebAccuracy of time delay depends on the accuracy of system clock. The Microprocessor is occupied simply in a waiting loop; otherwise it could be employed to perform other functions. The task of calculating accurate time delays is tedious.
