64-I/O Signal Descriptions
Signal Name
Description
RESET
Active Low (0) Reset pin resets all the registers in the device.
GOE 0, GOE1
Global Output Enable input pins.
Y0, Y1, Y2
Dedicated Clock Input – These clock inputs are connected to one of the clock inputs of all the GLBs in
the device.
BSCAN
Input – Dedicated in-system programming Boundary Scan enable input pin. This pin is brought low to
enable the programming mode. The TMS, TDI, TDO and TCK controls become active.
TDI/IN 0
TCK/IN 3
TMS/IN 1
TDO/IN 2
Input – This pin performs two functions. (1) When BSCAN is logic low, it functions as a serial data input
pin to load programming data into the device. When BSCAN is high, it functions as a dedicated input pin.
Input – This pin performs two functions. (1) When BSCAN is logic low, it functions as a clock pin for the
Boundary Scan state machine. (2) When BSCAN is high, it functions as a dedicated input pin.
Input – This pin performs two functions. (1) When BSCAN is logic low, it functions as a mode control pin
for the Boundary Scan state machine. (2) When BSCAN is high, it functions as a dedicated input pin.
Output/Input – This pin performs two functions. (1) When BSCAN is logic low, it functions as an output
pin to read serial shift register data. (2) When BSCAN is high, it functions as a dedicated input pin.
GND
Ground (GND)
VCC
Vcc
NC1
No Connect
I/O
Input/Output Pins – These are the general purpose I/O pins used by the logic array.
1. NC pins are not to be connected to any active signals, VCC or GND.
