Background Debug Mode Interface

Background Debug Mode Interface

Background Debug Mode (BDM) interface is an electronic interface that allows debugging of embedded systems. Specifically, it provides in-circuit debugging functionality in microcontrollers. It requires a single wire and specialized electronics in the system being debugged. It appears in many Freescale Semiconductor products.

The interface allows a Host to manage and query a Target. Specialized hardware is required in the target device. No special hardware is required in the host; a simple bi-directional I/O pin is sufficient.

Famous quotes containing the words mode and/or background:

    The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind. It is simply the mode in which all phenomena are reasoned about, rendered precise and exact.
    Thomas Henry Huxley (1825–95)

    In the true sense one’s native land, with its background of tradition, early impressions, reminiscences and other things dear to one, is not enough to make sensitive human beings feel at home.
    Emma Goldman (1869–1940)
