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 maintain signal integrity for the EMIF signals, serial termination resistors should be inserted into all EMIF output signal lines.
