-- Ensure we make a ground plane to reduce EMF
-  - Also make sure there are no traces running around the crystal oscillators for the MCU

+- From "Texas Instruments - SLAS655G...", Page 22:
+  - To improve EMI on the XT1 oscillator, the following guidelines should be observed:
+    - Keep the trace between the device and the crystal as short as possible.
+    - Design a good ground plane around the oscillator pins.
+    - Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
+    - Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
