Figure 11-11 on page 69 shows the setting of OCF0A and the clearing of TCNT0 in CTC mode and fast PWM mode
where OCR0A is TOP.

Register Description
11.9.1 TCCR0A – Timer/Counter Control Register A
Bits 7:6 – COM0A[1:0] : Compare Match Output A Mode
These bits control the Output Compare pin (OC0A) behavior. If one or both of the COM0A[1:0] bits are set, the OC0A
output overrides the normal port functionality of the I/O pin it is connected to. However, note that the Data Direction
Register (DDR) bit corresponding to the OC0A pin must be set in order to enable the output driver.
