Abstract
A circuit includes a timer to count edges of a clock from an initial count value to a terminal count value and to output a timer signal responsive to the terminal count value being reached. A random number generator circuit generates a plurality of random number values. Each generated random number value is sequentially loaded into the timer as one of the initial count value or the terminal count value. A capacitive sensor circuit determines, responsive to receipt of a plurality of timer signals from the timer, a touch event of a capacitive touch sensor.
