WebMay 25, 2024 · The purpose of an enable pin is to allow disabling the part (or some function of it) when you do not need it. Typically, you want the output(s) of a chip to be disabled while it is powering up, so you tie the enable pin through a resistor to "disabled", and later force it on with a GPIO output from your microcontroller, after the initialization is done.
