TCCR0 – Timer/Counter Control Register
Figure 14-11. Timer/Counter Timing Diagram, Clear Timer on Compare Match Mode, with Pres-
• Bit 7 – FOC0: Force Output Compare
The FOC0 bit is only active when the WGM00 bit specifies a non-PWM mode. However, for
ensuring compatibility with future devices, this bit must be set to zero when TCCR0 is written
when operating in PWM mode. When writing a logical one to the FOC0 bit, an immediate com-
pare match is forced on the Waveform Generation unit. The OC0 output is changed according to
its COM01:0 bits setting. Note that the FOC0 bit is implemented as a strobe. Therefore it is the
value present in the COM01:0 bits that determines the effect of the forced compare.
A FOC0 strobe will not generate any interrupt, nor will it clear the timer in CTC mode using
OCR0 as TOP.
The FOC0 bit is always read as zero.
• Bit 3, 6 – WGM0[1:0]: Waveform Generation Mode
These bits control the counting sequence of the counter, the source for the maximum (TOP)
counter value, and what type of Waveform Generation to be used. Modes of operation sup-
ported by the Timer/Counter unit are: Normal mode, Clear Timer on Compare Match (CTC)
mode, and two types of Pulse Width Modulation (PWM) modes. See
