Signal Descriptions
GOE 0 Global Output Enable input pin
Y0 Dedicated Clock input. This clock input is connected to one of the clock inputs of all the GLBs in the
device.
RESET/Y1 This pin performs two functions: (1) Active Low (0) Reset pin which resets all of the registers in the
device. (2) Dedicated Clock input.
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 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. (2) When BSCAN is high, it functions as a dedicated input
pin.
TMS/NC1Input – 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, this pin is not to be connected to any
active signals, VCC or GND.
TDO/IN 1 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.
TCK/Y2 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 Clock input.
GND Ground (GND)
VCC Vcc
NC1No Connect
I/O Input/Output pins – These are the general purpose I/O pins used by the logic array.
