Timer/Counter
The Timer/Counter (TCNT0) and Output Compare Register (OCR0A) are 8-bit registers. Inter-
rupt request (shorten as Int.Req.) signals are all visible in the Timer Interrupt Flag Register
(TIFR0). All interrupts are individually masked with the Timer Interrupt Mask Register
(TIMSK0). TIFR0 and TIMSK0 are not shown in the figure.
The Timer/Counter can be clocked internally, via the prescaler, or asynchronously clocked
from the XTAL1/2 pins, as detailed later in this section. The asynchronous operation is con-
trolled by the Asynchronous Status Register (ASSR). The Clock Select logic block controls
which clock source the Timer/Counter uses to increment (or decrement) its value. The
Timer/Counter is inactive when no clock source is selected. The output from the Clock Select
logic is referred to as the timer clock (clk
The double buffered Output Compare Register (OCR0A) is compared with the Timer/Counter
value at all times. The result of the compare can be used by the Waveform Generator to gen-
erate a PWM or variable frequency output on the Output Compare pin (OC0A).
