Consider an application where a PIT is used for clock generation in a digital device. Design a basic circuit using an 8253 timer to achieve a frequency of 1kHz if your clock frequency is 1MHz.
💡 Hint: Think about how to convert the clock cycle into the desired output frequency.
Discuss the advantages of using a PIT rather than a CPU for managing time-critical operations in embedded systems.
💡 Hint: Consider the operational load on the CPU and why delegation can enhance performance.
