VCC

Supply voltage for output drivers, 5V or 3.3V. All

VCCIO pins must be connected to the same voltage

level.

VCCIO

Ground (GND)

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 ISP state

machine. When BSCAN is high, it functions as a

dedicated input pin.

Dedicated Clock input. This clock input is connected to

one of the clock inputs of all the GLBs on the device.

This pin performs two functions:

Input — Dedicated in-system programming enable

input pin. This pin is brought low to enable the

programming mode. The TMS, TDI, TDO and TCK

controls become active.

TDI/IN 01

BSCAN

TMS/NC2

Input — When in ISP mode, controls operation of ISP

state machine.

- 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.

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.

TDO/IN 11

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 be routed to any GLB and/or I/O cell on the

device.

TCK/Y21

- Active Low (0) Reset pin which resets all of the GLB

and I/O registers in the device.
