"WebAug 7, 2012 · Timer 2 has both a prescaler and a postscaler. It can be used as the PWM time-base in addition to normal timing activities. There is no external clock input so it is driven solely by the internal processor clock. The prescaler functions just like the prescaler of the other two timers, Timer 0 and Timer 1, and can have prescale " - Counter clock prescaler

WebOct 15, 2024 · I need three timer : the first one must generate an interrupt every 1ms (I chose TIMER 1, an advanced control timer), the second one must generate an interrupt every 10ms (TIMER2, general purpose interrupt) and the third one must have its CNT counter incremented every 1µs (so interrupt is generated every 65.535 ms, as I am … WebA prescaler is essentially a configurable clock-divider circuit. Depending on the selected configuration bits, the prescaler output could be the same as the input signal, or it may have half the frequency, one-fourth the frequency, one-eighth the frequency, etc. Thus, a prescaler can extend a timer’s range by reducing its resolution.
