Description

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

Global Output Enable input pins.

Dedicated Clock Input – These clock inputs are connected to one of the clock inputs of all the GLBs 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 a serial data input pin

to load programming data into the device. 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

Boundary Scan 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 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.

Dedicated Input Pins to the device.

No Connect

Input/Output Pins – These are the general purpose I/O pins used by the logic array.

1. NC pins are not to be connected to any active signals, VCC or GND.
