§
PLLV and PLLG are not part of external voltage supply or ground. See the CLOCK/PLL documentation for information on how to connect these
pins.
A = Analog signal (PLL Filter)
#
The EMU0 and EMU1 pins are internally pulled up with 30-k
resistors; therefore, for emulation and normal operation, no external
pullup/pulldown resistors are necessary. However, for boundary scan operation, pull down the EMU1 and EMU0 pins with a dedicated 1-k
resistor.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k
IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)
