If the reset input is LOW for at least 24 crystal oscillator periods while the
oscillator is running, the device is reset (internal pull-up).
If the reset input is HIGH for at least 24 crystal oscillator periods while the
oscillator is running, the device is reset. This pin should be connected to
V
DDC
via a capacitor if an active HIGH reset is required (internal pull-down).
