NOTES
Power Supply Patterns power supply wire patterns (VCC patterns) should designed wide possible order reduce parasitic impedance. Switching Noise order reduce switching noise much possible, noise limit capacitor must connected between VCCD pins VCCA pins. this case, capacitor should connected pins side near possible.
