'''Background debug mode''' ('''BDM''') interface is an electronic interface that allows [[debugging]] of [[embedded system]]s. Specifically, it provides [[in-circuit emulator|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 bidirectional [[I/O port|I/O pin]] is sufficient.
