What does the Zero Flag indicate?
Think about what happens when you subtract equal numbers.
What is the Program Status Word (PSW)?
Remember, it helps in tracking the current execution context.
What does the Zero Flag indicate?
Consider basic arithmetic operations.
True or False: The Sign Flag reflects whether the last result was positive.
Think of how signed numbers are represented.
Assume you have a program with instructions that alter the PSW. If a program execution results in setting the Zero Flag, what will be the next instruction evaluated and how does it affect program flow?
Think of a scenario where a loop might terminate.
Design a pseudo-code that utilizes the flags within the PSW to control the flow of a simple program. Explain your design choices based on the flags used.
Think about how loops and accumulators work together.
