Bit 0 – CAPT: Interrupt Flag

Interrupt Flag

This bit is set when an interrupt occurs. The interrupt conditions are dependent on the Counter mode (CNTMODE) in TCB.CTRLB.

This bit is cleared by writing a '1' to it or when the Capture register is read in capture mode.

Input Capture Frequency Measurement Mode Set on edge when the capture register is loaded and count initialized, Flag clears when capture is read
Input Capture Pulse Width Measurement Mode Set on a edge when the capture register is loaded, previous edge initialized the count, Flag clears when capture is read
Input Capture Frequency and Pulse Width Measurement Mode Set on second (positive or negative) edge when the counter is stopped, Flag clears when capture is read
