17.7 Looking at registers
If you are debugging at assembly-language level using the Disassembly view, you will probably find it useful to see the
contents of the CPU's general registers. You can do this by using the Register window.
17.7.1 Opening the Register window
The Re
gister window displays the register data and flag data. You can change a register/flag value from the window.
To open the Register window, choose [View -> CPU -> Registers], or click the Registers toolbar button (
). The
Register window opens showing all of the CPU's general registers and values.
