The invention provides a debug function built-in type microcomputer that is capable of creating a readily analyzable debug environment and compressing output information, even when an output signal line having a bit width fewer than a bit width of a command bus is used to trace contents on the command bus. In a debug function built-in type microcomputer, a DBG (debug unit) outputs information to be traced, and status information indicative of contents of the information to be traced from a status generation circuit.
