Input - This pin is the Test Mode Select input, which is used to control the 1149.1 state machine.
Input - This pin is the Test Clock input pin, used to clock the 1149.1 state machine.
Input - This pin is the 1149.1 Test Data In pin, used to load data.
Output - This pin is the 1149.1 Test Data Out pin used to shift data out.
Input - Test Output Enable pin. TOE tristates all I/O pins when a logic low is driven.
Input - These two pins are the Global Output Enable input pins.
Dedicated Reset Input - This pin resets all registers in the devices. The global polarity (active high or
low input) for this pin is selectable.
Input/Output - These are the general purpose I/O used by the logic array.
