Output Compare Unit
cleared by software (writing a logical one to the I/O bit location). For measuring frequency only,
the trigger edge change is not required.
Table 17-3.
Note:
Table 17-4.
Note:
The comparator continuously compares the Timer/Counter (TCNTn) with the Output Compare
Registers (OCRnA and OCRnB), and whenever the Timer/Counter equals to the Output Com-
pare Registers, the comparator signals a match. A match will set the Output Compare Flag at
the next timer clock cycle. In 8-bit mode the match can set either the Output Compare Flag
OCFnA or OCFnB, but in 16-bit mode the match can set only the Output Compare Flag OCFnA
as there is only one Output Compare Unit. If the corresponding interrupt is enabled, the Output
Compare Flag generates an Output Compare interrupt. The Output Compare Flag is automati-
cally cleared when the interrupt is executed. Alternatively, the flag can be cleared by software by
writing a logical one to its I/O bit location.

noise canceler with these sources.
