The delay is calculated in 8085 by making the use of formulas. Because of the complexity of the mathematical operations a calculator may also be required.

Difference between delay subroutine and ordinary subroutine in context of 8085?

a subroutine is a portion of the code within a larger program which performs a specific function and is independent of remaining code.....delay routines are subroutines used for maintaining the timings of various operations in microprocessor


What is the function of READY pin of 8085?

The READY pin on the 8085 microprocessor is used to delay the completion of a bus transfer cycle. It is sampled by the 8085 at the falling edge of clock following ALE. If it is high, the cycle completes. If it is low, the cycle is extended by one clock, with all lines held steady - then it is sampled again at each of the next falling edges of clock until it is high. The purpose of READY is to allow (usually) memory devices to operate at a slower speed than the 8085.
