Maximum Ratings
This device contains circuitry protecting against damage due to high static voltage
or electrical fields. However, normal precautions should be taken to avoid
exceeding maximum voltage ratings. Reliability of operation is enhanced if unused
inputs are pulled to an appropriate logic voltage level (e.g., either GND or V
The suggested value for a pullup or pulldown resistor is 4.7 kΩ.

Internal Pull up resistor.
This input is 5 V tolerant.
Test Data Output—TDO is a test data serial output signal used for test
instructions and data. TDO is tri-statable and is actively driven in the shift-IR
and shift-DR controller states. TDO changes on the falling edge of TCK.
Test Mode Select—TMS is an input signal used to sequence the test
controller’s state machine. TMS is sampled on the rising edge of TCK.
Internal Pull up resistor.
This input is 5 V tolerant.

PLOCK—When this pin is configured as a PLL lock pin, this signal is
asserted high when the on-chip PLL enabled and locked and
de-asserted when the PLL enabled and unlocked. This pin is also
asserted high when the PLL is disabled.
