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.

WebOverflow flag. In computer processors, the overflow flag (sometimes called the V flag) is usually a single bit in a system status register used to indicate when an arithmetic overflow has occurred in an operation, indicating that the signed two's-complement result would not fit in the number of bits used for the result. WebIn signed arithmetic, the carry flag tells you nothing interesting. Overflow Flag. The rules for turning on the overflow flag in binary/integer math are two: If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)
