Figure 6-21 shows the recommended oscillator connections when MCU_OSC0_XI is connected to a 1.8-V LVCMOS square-wave digital clock source.
A DC steady-state condition is not allowed on MCU_OSC0_XI when the oscillator is powered up. This is not allowed because MCU_OSC0_XI is internally AC coupled to a comparator that can enter an unknown state when DC is applied to the input. Therefore, application software must power down MCU_OSC0 any time MCU_OSC0_XI is not toggling between logic states.
