8.4 PCB layout consideration
1. Caps for pins 9, 10 MUST have trace lengths LESS than 5mm.
2. The ground wires of pin1(VSS_LED), pin5(VSSD), pin6(VSSA) must be separated from PS2/USB
3. VSS_LED and VSSD must have trace lengths less than 100mm, VSSA must have trace lengths less
4. The trace lengths of OSCOUT, OSCIN must less than 6mm.
