To make the clock useful, the following will be an example of how to use Timer
1 to delay a certain amount of time. You will need the following information
* CPU freq (16MHz)
* Max timer value (0xFFFF or 65536)
* Chosen Prescaler (See above for prescaler values)
Divide the CPU freq by the chosen prescaler. Then divide that result through
the desired freqency. Be sure that the value is smaller than the max timer
value. If it is to large, choose a larger prescaler. Then place this in the
OCR** Register and enable the desired interrupt.
