Figure 6-27 shows the recommended oscillator connections when OSC1 is connected to a 1.8-V LVCMOS square-wave digital clock source.
A DC steady-state condition is not allowed on OSC1_XI when the oscillator is powered up. This is not allowed because OSC1_XI is internally AC coupled to a comparator that may enter a unknown state when DC is applied to the input. Therefore, application software should power down OSC1 any time OSC1_XI is not toggling between logic states.
