WebJan 14, 2024 · There are often several possible clock sources and one is selected with a switch or multiplexer. Sometimes an external clock source is an option. To increase the count range, the selected clock goes to a “prescaler” which divides the clock before it goes to a main counter. The dividing factor of the prescaler is usually limited to powers of 2. WebJun 25, 2024 · Timer is related to the internal frequency which is always Fosc/4. Clock source frequency (Crystal) Fosc = 12 MHz = 12000000 Hz. Therefore, Timer frequency : FTimer = Fosc / 4 = 12000000 / 4 = 3000000 Hz = 3 MHz. If Prescaler = 1:256, then. FTimer = 3000000 / 256 = 11718.75 Hz. So, the time interval :
