Input – This pin is the IEEE 1149.1 Test Mode Select input, which is used to control
the state machine.
Input – This pin is the IEEE 1149.1 Test Clock input pin, used to clock through the
state machine.
Input – This pin is the IEEE 1149.1 Test Data In pin, used to load data.
Output – This pin is the IEEE 1149.1 Test Data Out pin used to shift data out.
These pins are configured to be either Global Output Enable Input or as general I/O
pins.
