2.8.1 Minimum Event Duration Must Exceed the Selected Clock Period
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.
Work Around
Ensure that the high/low period of input events is equal to or longer than the selected clock source (CLKSEL in TCBn.CTRLA) period.
