Input – Global clock/clock enable inputs.
Input – Global MUX select inputs.
Input – Global output enable inputs.
Input – Global RESET signal (active low).
No connect.
GND – Ground.
VCC – The power supply pins for core logic.
VCC – The power supply for the JTAG logic.
VCC – The power supply pins for I/O Bank X.
Input – Defines the reference voltage for I/O Bank X.
Input – Test Mode Select input, used to control the 1149.1 state machine.
Input – Test Clock Input pin, used to clock the 1149.1 state machine.
Input – Test Data In pin, used to load data into device using 1149.1 state machine.
