CAUTION

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 VDD).

The suggested value for a pullup or pulldown resistor is 4.7 k

Ω.

PLOCK

Output

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.

Internal Pull down resistor.

This input is 5 V tolerant

Signal Description

TCK

Input

Test Clock—TCK is a test clock input signal used to synchronize the JTAG test

logic.

Internal Pull up resistor.

This input is 5 V tolerant.

TDI

Input

Test Data Input—TDI is a test data serial input signal used for test instructions

and data. TDI is sampled on the rising edge of TCK.

Internal Pull up resistor.

This input is 5 V tolerant.

TDO

Output

Tri-stated

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.

TMS

Input

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.
