Microprocessors Questions and Answers – Timings and Delays
Web100000 microsecond = 2 + 1,794 x count. Count = (100000-2)/ 1794 = 55.7402 = 56 decimal value = 38 H ( hexadecimal value) The maximum delay ( at count= ff H) is 2 + 1794 x 255 = 457,472 microsecond = 457.472 milli second = 0.45 second. When the system frequency is operating at 2 Mhz. WebDec 24, 2024 · A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1. When the computer restarts or is reset, the program counter normally reverts to 0. outsourcing aphg

WebA. Time Delay using NOP instruction: NOP instruction does nothing but take 4 T-states of processor time to execute. So by executing NOP instruction between two instructions we can get delay of 4 T-state where: 6.1 B. Time Delay Using Counter: Time delay can be created using counting process which means WebJul 30, 2024 · Microcontroller Microprocessor 8085. In this section we will see how to generate the time delay using 8085 programs. The delay will be used in different places to simulate clocks, or counters or some other area. When the delay subroutine is … Web2.2 Timer Delay Using Counters: Counting can create time delays. Since the execution times of the instructions used in a counting routine are known, the initial value of the counter, required to get specific time delay can be determined. 2.3 Timer Delay Using Nested Loops: In this, there are more than one loops. outsourcing a offshoring
