Challenge Problems
Push your limits with challenges.
Question 1
A microprocessor system uses an 8253 timer configured to generate interrupts every 1 ms for regular updates. If the input clock frequency is 1 MHz, what would be the initial count value loaded into the counter for this configuration?
💡 Hint: Remember how to convert timing requirements into timer counts.
Question 2
In a pit system featuring multiple counters, how would you program the counters to alternate generating square wave signals with different frequencies? Discuss the steps along with initial counts.
💡 Hint: Think about how frequency relates to periodic intervals and counts.
