Assignment 4 (25%) Part A - Design considerations (CO2 - C6) (30 marks) A1. In your own words, describe how interrupt works in a microcontroller. Use diagrams or analogies to aid your description. (8 marks) A2. In your opinion, compare and discuss the suitability of serial communication protocols in the following application cases: Case Application Serial Communication Protocol Case 1 Bidirectional Microcontroller to RS232 vs 12C microcontroller communication on the same PCB board Case 2 Bidirectional Microcontroller to multiple USB vs SPI sensors. Sensors are 1m away from microcontroller Case 3 Unidirectional Microcontroller to 12C VS RS485 peripheral communication. The environment is electronically noisy. (12 marks) A3. Based on your understanding of the microcontroller architecture, propose a microcontroller design with integrated ADC and WiFi module. Use an appropriate block diagram to demonstrate your design. (6 marks) A4. From your answer in Question A3, elaborate further to describe the one other change in the 8051 architecture to support the integrated modules. (4 marks)
