7.6 EBCortexA9_SysRegs component
The EB Cortex-A9 system registers component is a programmer's view model of the Cortex-A9
specific status and system control registers. It overrides some of the system registers provided
by the EB_SysRegs component. For a detailed description of the behavior of the component,
refer to the hardware documentation. See the RealView Emulation Baseboard User Guide (Lead
Free).
Figure 7-4 on page 7-13 shows a view of the component in System Canvas.
This component is written in LISA+.
