Answer C

c) Many (most?) PC processors are now 64 bit machines which means the default size of an unsigned int on those processors is 64-bits. An application needs to store time to the nanosecond. Can an entire year's worth of nanoseconds be stored in a 64-bit unsigned int? What is the longest period of time that can be stored to the nanosecond in a 64-bit unsigned integer? d) How would you configure Timer A2 to implement a clock with one second resolution. Write a C code segment (including the Timer A2 setup and TimerA2 ISR) implementing a clock that saves its time (count) UTC style in one unsigned 32-bit integer. Your timer should generate interrupts only once per second. What clock source and maximum count values should you use? Do you need leap counting? Explain
