Chip enable pin high active
WebDedicated active-low chip enable pin. When the nCE pin is low, the device is enabled. When the nCE pin is high, the device is disabled. In multi-device configuration, the nCE pin of the first device is tied low while its nCEO pin drives the nCE pin of … 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.
