7.9.4. Status and system control registers

For the hardware version of the Emulation Baseboard, the status and system control registers enable the processor to determine its environment and to control some on-board operations.

Note

Most of the EB FVP functionality is determined by its configuration on startup.

All EB system registers have been implemented in the system model, except for SYS_TEST_OSC[4:0], the oscillator test registers. Registers that are not implemented function as memory and the values written to them do not alter the behavior of the model.

In addition to the standard EB system control registers, an additional register has been modeled, based on the Platform Baseboard design. This is the SYS_RESETCTL register. For further information on this register see RealView Platform Baseboard Explore for Cortex-A9 User Guide.
