Device ground supply pins
3.3V supply to the device core.
+3.3V supply to the internal cloc�� multiplier. This pin requires a 100 nF decoupling capacitor.
Device analog ground supply for internal cloc�� multiplier
+3.3V supply to the ADBUS, ACBUS, BDBUS and BCBUS Interface pins �11...16, 18...23, 31...38, �1...�8).
Input to 12�H�� �scillator Cell. Connect 12 �H�� crystal across pins � and �, with suitable loading capacitors
to �ND. This pin can also be driven by an e��ternal 12 �H�� cloc�� signal. Note that the switching threshold of
this pin is VCC/2, so if driving from an e��ternal source, the source must be driving at �V C��S level, or a.c.
coupled to centre around VCC/2.
�utput from 12�H�� �scillator Cell. Connect 12 �H�� crystal across pins � and �, with suitable loading
capacitors to �ND. XT�UT stops oscillating during USB suspend, so ta��e care using this signal to cloc��
e��ternal logic.
External PLL filter circuit input� RC filter circuit must be fitted on this pin�
Puts the device into I.C. test mode. �ust be tied to �ND for normal operation.
Can be used by an e��ternal device to reset the VNC1L. This pin can be used in combination with PR��#
and the U�RT inter�ace to program firmware into the VNC1L� I� not required pull up to VCC via a 1�� kΩ
resistor.*
This pin is used in combination with the RESET# pin and the U�RT inter�ace to program firmware into the
VNC1L.*
