Compare - the value of compare register.

Timer Value - initial value of the counter register.

Compare Match interrupt - interrupt is generated at the coincidence.

Overflow interrupt - interrupt is generated on overflow.

Withdraw OCxx at the first match is reset in the second set.

Phase Correct PWM - first timer counts from 0 to 255, then from 255 to 0.

CTC - reset the coincidence, when the values in the counting register reaches the value in the register comparison counting register is reset to zero and the count starts again.

When the values in the counting register reaches compare registers (set in line Compare), timer exposes a certain logic level (set in the drop-down list Output) on the leg OCxx

Fast PWM - counter counts from 0 to 255, after the overflow is reset to 0 and the count repeated.

Normal top - counter counts from 0 to 255, after the overflow is reset to 0 and the count is repeated.

Mode - specifies the mode of operation of the timer counter.

Clock Value - selected prescaler clock, for example if we choose prescaler 8, then every 8 clock cycles will be considered as one.

TOSC1 pin - the timer will operate from an external quartz legged TOSC1, TOSC2.

System Clock - timer taktiruetsya frequency at which the microcontroller running.

Clock Source - clock source, here in the dropdown list, you can select.

Go to the tab Timers, further click on timer2. Run CodeVision AVR, create a new project and agree to the offer to run Code WizardAVR Let us consider the functional Timer/Counter1 in the microcontroller atmega8. Timers counters can be clocked from the internal oscillator clock frequency and counter input.

generate interrupts on some event, such as an overflow.Generate PWM signal at certain conclusions MK.

clocked from an external quartz clock on 32768 hertz.

They can still be divided into general purpose timers and watchdog timer, which is intended to reboot the MK when suspended. In all AVR microcontrollers have several built-in timers. The device I did, but it did not apply, and. Frankly, I wanted to try to include a TV with only 7 to 8 hours, and the rest of the time he had to be turned off. When I was first learning microcontrollers, I wanted to make hour timer, to control AC load.
