Q1. A) A microprocessor is wired into a sensing control circuit so that the memory locations 42 and contain the values 0 or 1. Memory location 50 is connected to a light switch. When the value in 50 is 1 the light is on and when it is 0 the light is off. Write a program to switch on the light on when the values in locations 42 and 43 are both 1, a switch off the light when the yalues in locations 42 and 43 are both 0

Computer Science - Assembly language code:
Q1. A)
A microprocessor is wired into a sensing control circuit so that the memory locations 42 and 43 each
contain the values 0 or 1.
Memory location 50 is connected to a light switch.
When the value in 50 is 1 the light is on and when it is 0 the light is off.
Write a program to switch on the light on when the values in locations 42 and 43 are both 1, and to
switch off the light when the values in locations 42 and 43 are both 0.
Only use the ARM assembly language instructions, MOV, JMP and JNZ.
Assume that the MOV instruction updates the flags with the status register.
