# TODO
# Design Reminders
- 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.
