Flag in microprocessor
WebParity flag. In computer processors the parity flag indicates if the numbers of set bits is odd or even in the binary representation of the result of the last operation. It is normally a single bit in a processor status register. For example, assume a machine where a set parity flag indicates even parity. If the result of the last operation ... WebThe FLAGS register is the status register that contains the current state of a x86 CPU. The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time. Some of those restrictions may include ...

WebRegisters receive binary data as input, checks the data available with them and process the input and deliver the output to the system as binary output. Now, a copy of the output is stored in the register. This helps the system to fetch the data for faster processing. Registers are classified based on their functionality and behavior. 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.
