WebJan 22, 2013 · TF (Trap Enable Flag, bit 8) TF controls the generation of exception 1trap when single-stepping through code. When TF is set, the 80386 generates an exception 1 trap after the next instruction is executed. When TF is reset, exception 1 traps occur only as a function of the breakpoint addresses loaded into debug registers DR0±DR3.
