A systems designer has developed a system to control streetlights represented by a combinational logic circuit shown in Figure 2. The streetlights can be turned on manually or using a timer. The system inputs consist of SWITCH connected to PORTA at address Ox1000C000, TIMER connected to PORTB located at address of Ox100OC004 and LIGHT SENSOR connected to PORTC located at address of Ox1000C008. The system output is a STREET LIGHTS connected to PORTF that located at memory address OX1000C00C. Write an assembly language program to implement the propose system. PORTA: O×1000C000 SWICH PORTF: OX1000C00C ORTB: O×1000C004 TIMER OR UGHTS AND PORTC: 0×1000C008
