 The PCNT peripheral is designed to count the number of rising and/or falling edges of an input signal. Each PCNT unit has two channels, which makes it possible to extract more information from two input signals than only one signal.

+This example shows how to make use of the HW features to decode the differential signals generated from a common rotary encoder -- [EC11](https://tech.alpsalpine.com/e/products/category/encorder/sub/01/series/ec11e/).
 
 The signals a rotary encoder produces (and what can be handled by this example) are based on a 2-bit gray code available on 2 digital data signal lines. The typical encoders use 3 output pins: 2 for the signals and one for the common signal usually GND.

-By configuring one of the EC11 GPIO (e.g. `EXAMPLE_EC11_GPIO_A`) as a wake up source, we can make the rotary encoder wake the system from light sleep. This example can illustrate this feature if you enable the `EXAMPLE_WAKE_UP_LIGHT_SLEEP` from the menuconfig.
