This pin performs one of two functions. It can be programmed to function as a Global Output Enable
pin or a Dedicated Input pin.
This pin performs one of two functions. It can be programmed to function as a Global Output Enable or
a Dedicated Clock input. This clock input is connected to one of the clock inputs of all GLBs on the
device.
This pin performs two functions: (1) Dedicated clock input. This clock input is brought into the Clock
Distribution Network and can optionally be routed to any GLB and/or I/O cell on the device. (2) Active
Low (0) Reset pin which resets all of the registers in the device.
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.
Input – This pin performs two functions. When BSCAN is logic low, it functions as an input pin to load
programming data into the device. TDI/IN0 is also used as one of the two control pins for the ISP State
Machine. When BSCAN is high, it functions as a dedicated input pin.
Input – This pin performs two functions. When BSCAN is logic low, it functions as a pin to control the
operation of the ISP State Machine. When BSCAN is high, it functions as a dedicated input pin.
Output/Input – This pin performs two functions. When BSCAN is logic low, it functions as an output pin
pin to read serial shift register data. When BSCAN is high, it functions as a dedicated input pin.
Input – This pin performs two functions. When BSCAN is logic low, it functions as a clock pin for the
Serial Shift Register. When BSCAN is high, it functions as a dedicated clock input. This clock input is
brought into the Clock Distribution Network and can optionally be routed to any GLB and/or I/O cell on
the device.

Input – This pin performs two functions. When BSCAN is logic low, it functions as a mode control pin for
the Boundary Scan state machine. When BSCAN is high, it functions as a dedicated input pin.
Output/Input – This pin performs two functions. When BSCAN is logic low, it functions as an output pin
to read serial shift register data. When BSCAN is high, it functions as a dedicated input pin.
