Event detection will fail if TCBn receives an input event with a high/low period shorter than the period of the selected clock source (CLKSEL in TCBn.CTRLA). This applies to the TCB modes (CNTMODE in TCBn.CTRLB) Time-Out Check and Input Capture Frequency and Pulse-Width Measurement mode.
Ensure that the high/low period of input events is equal to or longer than the period of the selected clock source (CLKSEL in TCBn.CTRLA).
