An input capture has occurred.To clear this bit, first read the SR register, then read or

write the low byte of the ICR2 (ICLR2) register.

Bit 3 = OCF2 Output Compare Flag 2.

No match (reset value)

The content of the free running counter has matched the content of the OCR2 register.

To clear this bit, first read the SR register, then read or write the low byte of the OCR2

(OCLR2) register.
