The Prescaler
The prescaler is an 8-bit device that is used in the TIMER mode only. The
prescaler is programmed by the CPU through the Channel Control register
to divide its input, the System clock (0), by 16 or 256. The output of the
prescaler is then fed as an input to clock the down-counter. Each time that
