One Shot Fall


The One Shot Fall block outputs a trigger signal based upon the falling edge of the input signal. At the first falling edge of the input signal, the output signal will go high and remain high.In One Shot Fall Reset The output signal will remain high until a non-zero input signal is seen on the reset pin. The falling edge of the input signal is defined as any input signal level value changing to a lower signal level value.
