Global Output Enable input pins.
Dedicated Clock input. This clock input is connected to one of the
clock inputs of all of the GLBs on the device.
Active Low (0) Reset pin which resets all of the registers in the device.

VCCIO Supply voltage for output drivers, 5V or 3.3V. All VCCIO pins must
be connected to the same voltage level.
Input - This pin performs two functions. When BSCAN is logic low, it
functions as a pin to control the operation of the JTAG 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 an input pin to load programming data into the device.
TDI/IN0 also is used as one of the two control pins for the JTAG state
machine. When BSCAN is high, it functions as a dedicated input pin.
Input - Dedicated in-system programming enable input pin. This pin is
brought low to enable the programming mode. The TMS, TDI, TDO
and TCK options become active.
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.
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 input pin.
