(1) Maximum frequency of operation of the entire device cannot be exceeded.
(2) When HFXTBYPASS is set, HFXT circuits are automatically powered down. Input signal is a digital square wave with parametrics
defined in the Schmitt-trigger Inputs section of this datasheet. Duty cycle requirements are defined by DC_{HFXT, SW}.
