RTCK

Returned JTAG Test Clock

 

 

 

 

 

 

 

 

 

This input to the BDI2000 connects to the target RTCK line.

Vcc Target

1.8 – 5.0V:

 

 

 

 

 

 

 

 

 

This is the target reference voltage. It indicates that the target has power and it is also used

 

 

 

 

 

 

 

to create the logic-level reference for the input comparators. It also controls the output logic

 

 

 

 

 

 

 

levels to the target. It is normally fed from Vdd I/O on the target board.

 

 

 

 

 

 

 

 

3.0 – 5.0V with Rev. A/B :

 

 

 

 

 

 

 

 

 

This input to the BDI2000 is used to detect if the target is powered up. If there is a current

 

 

 

 

 

 

 

limiting resistor between this pin and the target Vdd, it should be 100 Ohm or less.

TCK

JTAG Test Clock

 

 

 

 

 

 

 

 

 

This output of the BDI2000 connects to the target TCK line.

TRST

 

 

 

 

 

 

 

 

 

This open-drain / push-pull output of the BDI2000 resets the JTAG TAP controller on the

 

 

 

 

 

 

 

 

target. Default driver type is open-drain.
