(1)Oscillator ground must be kept separate from other grounds and connected directly to the crystal load capacitor ground (see Section 5.5.1).

(2)These I/O specifications apply to regular 3.3 V I/Os and do not apply to DDR2/mDDR, USB I/Os. DDR2/mDDR I/Os are 1.8 V I/Os and adhere to JESD79-2A standard, USB I/Os adhere to USB2.0 spec.

(3)See Section 5.9.2.4. Also, resistors should be E-96 spec line (3 digits with 1% accuracy).

(4)Connect USB_R1 to VSS_USB_REF via 10K ohm, 1% resistor placed as close to the device as possible. .
