8.3.2 Design Layout Recommendations

When designing the LCD interface, consider the following recommendations:

Match the LCD signals lengths to within 50 mils. Affected PIOs in the example above are PC0 to PC23, PC27 to PC30.
Place the clock line (PC30) at least three times the trace width away from other signals for noise immunity.
Place data signals at least two times the trace width away from any other data trace.
Design data signals at least two times the trace width away from any copper plane.
