Table 4 shows the pin numbering for the Standard EJTAG (EJT) connector. All the even numbered pins are connected to GROUND. The two right-
hand most columns show the target signal direction and the recommended termination at the target. Target termination resistors may be internal to the
chip or external on the board.

1.
The value of the series resistor may depend on the actual PCB layout situation.
2.
TCK pull-up resistor is not required according to the JTAG (IEEE1149) standard. It is indicated here to prevent a floating
CMOS input when the EJTAG connector is unconnected.
