Although the impedance of a ground plane is low it is, of course, not zero. Therefore, any noise current in the ground plane causes a voltage drop in the ground. Figure 8-38 shows the grounding scheme for slow (low frequency) clock generated from the internal oscillator.
Figure 8-39 shows the grounding scheme for high-frequency clock.
