a question regarding FTM on Kinetis:
40.4.19 Input Capture Filter Control (FTMx_FILTER)
This register selects the filter value for the inputs of channels.
Channel x Input Filter
Selects the filter value for the channel input.
The filter is disabled when the value is zero.
There are 4 bits for the filter values. How is the "effect" of filtering per 1 LSB of those 4 bits?
Does it basically tell how long the input signal have to be minimum (measured in system clock cycles) to go through the filter?
