Webcome before (prescaler) or after (postscaler) the timer/counter value register. A scaler works by dividing an input signal by a specific value. For example, if we have a periodic input signal with a frequency of 1000 Hz (1000 Hz = 1/1 mS) and passed it through a prescaler set to 2:1, the value in the timer/counter value register would increment ... 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. ugh1001w

Timers prescale and postscale - Electrical Engineering Stack Exchange

WebOct 7, 2024 · The prescaler is used to divide the frequency of the base signal (usually 80 MHz), which is then used to increment / decrement the timer counter [2]. Since the prescaler has 16 bits, it can divide the clock signal frequency by a factor from 2 to 65536 [2], giving a lot of configuration freedom. WebJan 8, 2024 · Timers prescale and postscale. So i understand that a prescaler divides a clock, and PR2 is the period register which when the timer TMR2 reaches the value it increments from 0. Why is a post scaler needed to divide a non-clock signal. From the diagram it looks like the post scaler is trying to divide the comparator signal for when the …
