Write and test a program using Systick interrupts and the precision clock to toggle the Tiva LEDS (white, off, white, off, ) every 0.7 seconds. Show the math used to get an interrupt every 0.7 seconds. What is the longest toggle time (to nearest microsecond) you could get using Systick interrupts directly? Your program can be written using a easily modified subset of your Lab 7 code.
