SET 4C 4. Figure 3 shows an Analog-to-Digital Converter (ADC) connected to an 8086 system. Based on the figure, answer the following questions, (a) Deternine the ADC address. (3 marks) (b) Determine the address for interrupt (INT) of the ADC. (3 marks) (e) Write an assembly langttage procedure to start conversion and read the converted digital data. (4 marks) (d) The ADC connection is modified such that the INT signal is required to be connected to INT 8086 input pin. Given the system has THREE (3) other interrupt inputs with interrupt vector 56H, 57 and 58H Suggest an interrupt structure so that the 8086 systems can handle all interrupts. (4 marks) () Draw the schematic of the interrupt structure as you suggest in (). (6 marks) (ii) Discuss how tle interrupt structure you choose in (1) determines the interrupt priority. (4 marks) (4 marks) (iv) Suggest an interrupt vector for the ADC. (2 marks) (v) Provide address for all interrupt vectors in the system.
