Description
+3.3V supply to the internal clock multiplier. This pin requires a 100nF decoupling
capacitor
Device analogue ground supply for internal clock multiplier
+3.3V supply to the ADBUS, ACBUS, BDBUS and BCBUS Interface pins (11..16,
18..23, 31..38, 41..48). Leaving the VCCIO unconnected will lead to unpredictable
operation on these interface pins.
Description
Input to 12MHz Oscillator Cell. Connect 12MHz crystal across pins 4 and 5, with
suitable loading capacitors to GND. This pin can also be driven by an external 12MHz
clock signal. Note that the switching threshold of this pin is VCC/2, so if driving from
an external source, the source must be driving at +3.3V CMOS level or AC coupled to
centre around VCC/2
Output from 12MHz Oscillator Cell. Connect 12MHz crystal across pins 4 and 5, with
suitable loading capacitors to GND. XTOUT stops oscillating during USB suspend, so
take care using this signal to clock external logic
External PLL filter circuit input. RC filter circuit must be fitted on this pin
Puts the device into IC test mode. Must be tied to GND for normal operation
Can be used by an external device to reset VNC1L. This pin can be used in
combination with PROG# and the UART interface to program firmware into VNC1L. If
not required pull-up to VCC via a 47kΩ resistor.*
This pin is used in combination with the RESET# pin and the UART interface to
program firmware into VNC1L.*
