High Quality Content by WIKIPEDIA articles! Debug register is a register used by a processor for program debugging. On the x86 architecture, these are named DR0...DR7. The debug registers allow programmers to selectively enable various debug conditions associated with the four debug addresses. Six of these registers are used to control debug features. These registers are accessed by variants of the MOV instruction. A debug register may be either the source operand or destination operand. The debug registers are privileged resources; the MOV instructions that access them can only be executed at privilege level zero. An attempt to read or write the debug registers when executing at any other privilege level causes a general protection fault.
