This is because the CPU clock, running at 168 MHz, is divided by -2 and then by prescaler+1, giving a freqency of 168 MHz/2/(83+1)=1 MHz +2 and then by prescaler+1, giving a frequency of 168 MHz/2/(83+1)=1 MHz for timer 2. The period is set to a large number so that the timer can count up to a large number before wrapping back around to zero. In this case it will take about 17 minutes before it cycles back to |
