Register Windows
A Register window displays register contents and allows you to edit those contents. Different types of Register windows are available for different build targets. This section describes the following Register windows:
General Registers window
The General Registers window (Figure 11.27) displays CPU registers and allows you to edit register contents. To open a General Registers window, choose Window > Registers Windows > General Registers.
NOTE
The appearance of the General Registers window depends on the build target. The build target also determines the commands in the Registers Windows submenu. If a submenu is unavailable, simply choose Register Window to see the window shown in Figure 11.27.
General Registers Window (Windows):
To change a register value, double-click the value or select the register and press Enter/Return. You can then type in a new value.

FPU Registers window
The FPU Registers window (Figure 11.29) displays FPU registers and allows you to edit register contents. To open an FPU Registers window, choose Window > Registers Windows > FPU Registers.
