† 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.

External clock source (as opposed to internal)
On this device, this pin does not have an internal pulldown (IPD). For proper device opera-
tion, the CLKS1 pin should either be driven externally at all times or be pulled up with a
I IPD
10-kΩ resistor to a valid logic level. Because it is common for some ICs to 3-state their out-
puts at times, a 10-kΩ pullup resistor may be desirable even when an external device is
driving the pin.
