†I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal (PLL Filter)

‡IPD = Internal pulldown, IPU = Internal pullup. [To oppose the supply rail on these IPD/IPU signal pins, use external pullup or pulldown resistors no greater than 4.4 kΩ and 2.0 kΩ, respectively.]

§To ensure a proper logic level during reset when these pins are both routed out and 3-stated or not driven, it is recommended that an external 10-kΩpullup/pulldown resistor be included to sustain the IPU/IPD, respectively.
