8051 microcontroller C program to toggle only pin P1.3 continuously every 250 ms. Use timer 0, mode 2 to create the delay. Consider the clock frequency as 11.0592 MHz

Computer science subjects (DLD) Hello, i m posting it 2nd time . Please dont give me incorrect answer, i will downvote it right away.

11. Find the output function of the following logic circuits: A A C В C A C A В TT

Design a modulo-6 counter, which counts in the sequence 0, 1, 2, 3, 4, 5, 0, 1, .... The counter counts the clock pulses if its enable input, w, is equal to 1. Use D flip-flops in your circuit. Repeat Problem 6.23 using JK flip-flops. Repeat Problem 6.23 using T flip-flops.

4) Design a combinational logic circuit using 4 to 1 MUX with four-bit number as input, A, B, C, D whose outputs are P, Q, R, S which represents the ones complement of the input.

I need help with a clear explanation, please

Consider a 5-bit right shift register each shifting data to the right for every clock pulse. The serial input A is derived by using NAND gates as shown in figure. If the initial content of the counter is 10001 at QOQ1Q2Q3Q4 by applying the clock signal then after how many clock pulse circuit is back to the initial state? Qo Q Q2 Q Q4 Register

solve this problem but use T flip-flops

Every Linear Feedback Shift Register has at least one invalid initial state (when all the terms are zero). Describe an LFSR which has both valid states and invalid states in addition to the trivial one. For your given system, determine all invalid states, and the periods for the valid states.

4. Find the values to be loaded in the THO and TLO register in mode-2 of the 8051 microcontroller with a crystal oscillator frequency 12MHz so that it gives a delay of 50 uSec.
