Cleared to 0 by the processor for debug exceptions inside RTM transactions, [f] set to 1 for all debug exceptions outside transactions. On processors without TSX, bit 16 of DR6 is a read-only bit, acting in the same way as bits 31:17. 31:17 — Reserved.

Microsoft Script Debugger is relatively minimal debugger for Windows Script Host-supported scripting languages, such as VBScript and JScript.Its user interface allows the user to set breakpoints and/or step through execution of script code line by line, and examine values of variables and properties after any step.
Without hardware support (and in multitasking environments), debuggers have to implement breakpoints in software. For instruction breakpoints, this is a comparatively simple task of replacing the instruction at the location of the breakpoint by either: an instruction that calls the debugger directly (e.g. a system call, or int3 in case of x86) or

The INT3 instruction is a one-byte-instruction defined for use by debuggers to temporarily replace an instruction in a running program in order to set a code breakpoint. The more general INT XXh instructions are encoded using two bytes. This makes them unsuitable for use in patching instructions (which can be one byte long); see SIGTRAP.
