Abstract
A method and implementing system are provided in which a service processor is implemented in addition to system processors. The service processor is enabled to access system on-chip registers to acquire system data through the use of the system JTAG bus connections. In one embodiment, logic is provided to determine concurrent calls for use of the same registers by both the system processor(s) and also by the service processor through the JTAG bus. In case of concurrent requests, the JTAG data are held so as not to interfere with system operations until the system processor's use of the registers has been completed.
