Abstract
In one embodiment, a system comprises JTAG functionality that implements at least a portion of a JTAG protocol. The JTAG functionality supports a test data in (TDI) line, a test data out (TDO) line, a test rest (TR) line, a test mode state (TMS) line, and a test clock (TCLK) line. The system further comprises a debug interface to communicatively couple the system to a debug device external to the system. The debug interface comprises a transmit (TX) line, receive (RX) line, and a clock (CLK) line. The system transmits data output by the JTAG functionality on the TDI input on the RX line of the debug interface and receives data from the debug device on the TX line of the debug interface and provides the received data to the JTAG functionality on the TDO line, TR line and the TMS line.
