Counter Input Modes 5 Tips for Making High-Speed Counter Measurements ( > 1 MHz ) …… 5-1 Debounce Module …… 5-1 Terms Applicable to Counter Modes

Trigger After Stable Mode In the “Trigger After Stable” mode, the output of the debounce module will not change state until a period of stability has

T2 – During time period T2, the input signal is not stable for a length of time equal to T1 (the debounce time setting for this example.) Therefore,

Use trigger before stable mode when the input signal has groups of glitches and each group is to be counted as one. The trigger before stable mode w
