9   rising and/or falling edges of an input signal.
14   Each pulse counter unit has a 16-bit signed counter register.
19   Each channel has two inputs: a signal input that accepts signal edges
20   to be detected, as well as a control input that can be used to enable
21   or disable the signal input.
29   Example: Use PCNT to read a rotary-enconder
31   The mapping between signal and control input and the pin is done through pinctrl:

43   Note: Check espressif,esp32-pinctrl.yaml for complete documentation regarding pinctrl.
