Algorithm for calculating prescaler and period of a timer

WebOct 3, 2013 · The TMR0 prescaler is set (via 4 bits in the OPTION register) to divide-by-1, -2, -4, -8, -16, -32, -64, -128, or -256. The TMR0 input clock (1 MHz in your case) is passed to the prescaler, whose divided-down output is then fed to the TMR0 register. For example, if the TMR0 prescaler is set to divide-by-4 and the PIC is running at 4 MHz, the ... WebOct 29, 2024 · This means by default, the counter in timers counts up at 48MHz, which is obviously way too fast. Fortunately, we can slow down this clock by dividing it with a custom value. This value is called the prescaler.
