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. Web• Timer 4: 8-bit timer with a 6-bit prescaler • Timer 5: 8-bit timer with a 6-bit prescaler • Timer 6: 8-bit timer with a 6-bit prescaler (with toggle output) • Timer 7: 8-bit timer with a 6-bit prescaler (with toggle output) • Base timer 1) The clock can be selected from among a subclock (32.768kHz crystal oscillator), low-speed RC
