QUESTION LI If a Crystal of 23.91 MHz is used in an 8051 micro controller, what will be the machine cyle time. The answer must be given in ns. QUESTION 1.2 If you use Timer O in 16 bit mode, and use a Crystal of 13.01 MHz, what will be the start point if you want a delay of 50 ms before roll over? QUESTION 1.3 Use Timero in 8 bit Auto reload mode with a Crystal of 13.01 MHz. If your Start up values in TLO and THO is 128, what will be the total delay if the timer has rolled over 12 times and is then stopped? The answer must be given in us. QUESTION 1.4 In a 16 bit timer, what will the Start point be if you want a total delay of 2.4 seconds, the Start point is reloaded after every roll over, and you want 100 roll overs to occur. Use a 13.74 MHz crystal. QUESTION 1.5 If Timer 1 is placed in Counter mode as well as in 8 bit Auto reload mode. Timer O is placed in Timer mode as well as in 16 bit mode. What is the hex value in TMOD. Use the format as Ox?? QUESTION 1.6 If Timer 0 and Timer I interrupt must be enabled as well as External interrupt 1, what must be the value of IE to enable these interrupts? Answer in the format Ox?? Micro Controller Design Systems - MCD2601 - Major Test 2 2 of 10 QUESTION 2181 Write a program in Cor Assembly language which will indicate the number of cars driving past a point in 1 hour. At the end of each hour, the number of cars should be sent to an LCD display. Use a function called "void LCD Display(unsigned int CarCount)". You do not need to write the function. The display should only be updated every hour, meaning that a new count will the initiated again. A sensor connected to P3.4 (Counter O input) will produce a complete pulse every time a car passes the sensing point. Activate Counter 0 in 16-bit mode. Use timer 1 in 16-bit timer mode to generate the time delay.Use a 50 ms delay before roll over. Use interrupts. Assume that the maximum cars passing the sensingpoint in an hour will be 4000, The crystal frequency is 12 MHz.
