P i n D e s c r i p t i o n  
The Probe A pin is used to output data from any user-defined  
design node within the device. This independent diagnostic  
pin is used in conjunction with the Probe B pin to allow  
real-time diagnostic output of any signal path within the  
device. The Probe A pin can be used as a user-defined I/O  
when debugging has been completed. The pins probe  
capabilities can be permanently disabled to protect the  
programmed designs confidentiality. PRA is active when the  
MODE pin is HIGH. This pin functions as an I/O when the  
MODE pin is LOW.  
C LK  
C lo c k (In p u t )  
TTL Clock input for global clock distribution network. The  
Clock input is buffered prior to clocking the logic modules.  
This pin can also be used as an I/O.  
DC LK  
Dia g n o s t ic C lo c k (In p u t )  
TTL Clock input for diagnostic probe and device  
programming. DCLK is active when the MODE pin is HIGH.  
This pin functions as an I/O when the MODE pin is LOW.

The Probe B pin is used to output data from any user-defined  
design node within the device. This independent diagnostic  
pin is used in conjunction with the Probe A pin to allow  
real-time diagnostic output of any signal path within the  
device. The Probe B pin can be used as a user-defined I/O  
when debugging has been completed. The pins probe  
capabilities can be permanently disabled to protect the  
programmed designs confidentiality. PRB is active when the  
MODE pin is HIGH. This pin functions as an I/O when the  
MODE pin is LOW.  
I/O  
In p u t /O u t p u t (In p u t , O u t p u t )  
I/O pin functions as an input, output, three-state, or  
bidirectional buffer. Input and output levels are compatible  
with standard TTL and CMOS specifications. Unused I/O pins  
are automatically driven LOW by the ALS software.  
MO DE  
Mo d e (In p u t )  
The MODE pin controls the use of multifunction pins (DCLK,  
PRA, PRB, SDI). When the MODE pin is HIGH, the special  
functions are active. When the MODE pin is LOW, the pins  
function as I/O. To provide Actionprobe capability, the MODE  
pin should be terminated to GND through a 10K resistor so  
that the MODE pin can be pulled high when required.  
S DI  
S e r ia l Da t a In p u t (In p u t )  
Serial data input for diagnostic probe and device  
programming. SDI is active when the MODE pin is HIGH. This  
pin functions as an I/O when the MODE pin is LOW.

Notes:  
1. Stresses beyond those listed under “Absolute Maximum Ratings”  
may cause permanent damage to the device. Exposure to  
absolute maximum rated conditions for extended periods may  
affect device reliability. Device should not be operated outside  
the Recommended Operating Conditions.  
2. V = V , except during device programming.

3. Device inputs are normally high impedance and draw  
extremely low current. However, when input voltage is greater  
than V + 0.5 V or less than GND – 0.5 V, the internal protection  
CC  
diode will be forward biased and can draw excessive current.
