NOTES for JTAG signal designed:
- It is recommended to design your target board as 20pins, then Emlink
- If designed to other pins (only connect the active signals’ pin), then
- There is 10Kohm resistor pulled up inside Emlink nTRST pin, please do
- All signal ‘GND’ should be connect to target board ground, 0V.

Test Reset (JTAG): Resets the test state machine. The TRST signal must be
asserted after power up to ensure proper JTAG operation. The TRST signal has a
10 Kohm internal pull-up resistor. Please do not pulled down with resistor on
this pin in board side, but let it open or pulled download >10Kohm.
Test Clock (JTAG): Provides an asynchronous clock for JTAG boundary scan.
Test Data Input (JTAG): A serial data input of the boundary scan path. This
signal has a 10 kW internal pull-up resistor.
Test Data Output (JTAG): A serial data output of the boundary scan path.
Test Mode Select (JTAG): Controls the test state machine. This signal has a
10 kW internal pull-up resistor.
The target system reset signal. ICE can reset target via this signal.
No connect on Emlink side.
