Abstract: A Joint Test Access Group (JTAG) device can include a Joint Test Access Group (JTAG) port, transport layer circuitry to provide a communication to and from a debug device, and packet interpreter circuitry communicatively coupled between the JTAG port and the transport layer circuitry, the packet interpreter circuitry to translate data in a packet from the debug device into a sequence of bits to be provided to the JTAG port.

Abstract: An Automated Dynamic low voltage monitoring (LVM) based Low-Power (ADLLP) debug capability for a system-on-chip (SoC) as well as the open/closed-chassis platform for faster TTM (Time to Market) of the final platform or system. ADLLP Debug is achieved by detection of the probe connection between a target system (e.g., SoC) and debug host system. A user can dynamically override the power, clocks and LVM for intellectual property (IP) blocks not part of the debug trace by instructing a Power Management Controller (PMC) via the Inter Processor Communication (IPC) mailbox (or any other suitable mailbox driver) to set the registers in a Target Firmware (TFW) based on the probe and debug use-case.

Abstract: A first state of an interconnect protocol is entered. A particular signal is sent according to the protocol to a device over a link. During the first state, it is detected that a response to the particular signal is received in the first state. It is determined that the device supports a configuration mode outside the protocol based on the received response. The configuration mode is entered based on the response. One or more in-band configuration messages are sent within the configuration mode.
