Consider a microprocessor based board which has 7-segment and Led is connected to it. Design an assembly language code such that input from user is taken; when user presses “1” “5410” should display on 7-seg Display and when user press 2 leds should glow 5 times in a loop. If any other key is pressed no action should be taken

(d) In a certain clock generation circuitry, the input range of the PLL is 3MHZ – 6MHZ. If the input clock is 16MHZ. what are the best values for the divider and PLL setting to get 20MHZ at the output of the clock generation circuitry?

Q4 Table Q4 shows the mode and task that need to be implemented using PIC18F452. (a) Mode Switch (SW1) 1 Press 1 time 2 Press 2 times Table Q4 Task Move the LED right to left and continue back from left to right. Control the duty cycle of PWM for the period of 2 ms. You are given 1 switch, 1 potentiometer and 8 LEDs, sketch the interface between the components and PIC microcontroller. (b) Construct a C18 program to control the tasks in Table Q4. (4 marks)

Figure 1 shows a block diagram of the 8051 microcontroller. Briefly describe thefunction of each of the numbered elements in the diagram as well as the T0, EA,RST, ALE, PSEN, and INT0 input/output pins.
