A temperature monitoring system has been developed by a local company which is RACOM SDN. BHD. The system is based on MC68000 has devices which are located at address as below: Table Q4: Address of Devices used in the system Devices Address ROM chips contain a total of 16k bytes $10000 RAM chips contain a total of 32k bytes $20000 Temperature sensor, 8 bits $40000 Liquid Crystal Display (LCD), 8 bits $50000 a b) The monitoring system needs to display the measured temperature in Celsius (C) unit. But, the temperature sensor gives measurement in Fahrenheit (F). The equation for the conversion is as show below: T.=5(T;- 3276 Where Te is temperature in Celsius (C) while Tp is in Fahrenheit (F). Thus, based on the equation above, develop a microprocessor coding by using Arithmetic Instruction Sets to convert Fahrenheit to Celsius unit. The answer of the converted unit (Celsius, C) should display at LCD. Treat all numbers as unsigned number. (10 marks) [25 marks]
