At the end of the do$\_$work$()$ function, implement a kick$\_$dog$()$ to call the set$\_$timer$\_$count

function to reset the count back to $0.$ This will prevent the timer from expiring under normal

circumstances. If the program gets stuck in the middle of do$\_$work$()$ and kick$\_$dog$()$ is not

run, then the timer will expire and the program will get rebooted at the timer ISR.
