12
*MULTSEL/PCICLK2
I/O
3.3V LVTTL input for selection the current multiplier for CPU outputs / 3.3V PCI clock output.
13
GNDPCI
PWR
Ground pin for the PCI outputs
14
PCICLK3
OUT
PCI clock output.
15
PCICLK4
OUT

23
VDD
PWR
Power supply, nominal 3.3V
24
GND
PWR
Ground pin.
25
IREF
OUT
This pin establishes the reference current for the CPUCLK pairs. This pin requires a fixed
precision resistor tied to ground in order to establish the appropriate current.
26
*(PD#)RESET#
I/O
Asynchronous active low input pin used to power down the device into a low power state.
This input is activated by the MODE selection pin / Real time system reset signal for
frequency gear ratio change or watchdog timer timeout. This signal is active low.
27
