Timer/Counter Timing Diagrams
• OCR0A changes its value from MAX, as in
• The timer starts counting from a value higher than the one in OCR0A, and for that reason
The timer/counter is a synchronous design, and the timer clock (clkT0) is, therefore, shown as
a clock enable signal in the following figures. The figures include information on when interrupt
flags are set.
tion.The figure shows the count sequence close to the max value in all modes other than
phase correct PWM mode.
