Displays the current state of the flags and information bits contained in the 32-bit register EFL. After you execute an instruction, the Flags pane highlights in red any flags that have changed value since the program was last paused.

The Flags pane is located at the upper right when the Entire CPU view is displayed (View > Debug Windows > CPU Windows > Entire CPU).

The processor uses the bits in this register to control certain operations and indicate the state of the processor after it executes certain instructions. Pass the mouse over a flag to display the flag name.

Item Description

Toggle Flag

Toggles the selected flag or bit. For single-bit flags, Toggle changes the value from 0 to 1, or from 1 to 0. For multi-bit flags, Toggle cycles through all possible values. The flag and information bits in the Flags pane typically hold a binary value of 0 or 1, except for the IO flag, which can have the values 0, 1, 2, or 3. For the IO flag, Toggle cycles through the four possible values. .
