Global Output Enable input pins

Active Low (0) Reset pin which resets all the registers in the device.

W Dedicated Clock input. This clock input is connected to one of the clock

E inputs of all the GLBs in the device.

N 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.

R TDI/IN 0

16

Input — This pin performs two functions. When ispEN is logic low, it

functions as a serial data input pin to load programming data into the

device. When ispEN is high, it functions as a dedicated input pin.

O TCK/IN 3

61

59

Input — This pin performs two functions. When ispEN is logic low, it

Ffunctions as a clock pin for the ISP/Boundary Scan state machine.

When ispEN is high, it functions as a dedicated input pin.

TMS/IN 1

43

37

Input — This pin performs two functions. When ispEN is logic low, it

Efunctions as a mode control pin for the ISP/Boundary Scan state

machine. When ispEN is high, it functions as a dedicated input pin.

87

Output/Input — This pin performs two functions. When ispEN is logic

low, it functions as an output pin to read serial shift register data. When

ispEN is high, it functions as a dedicated input pin.
