Description: System Services
interface consists of an asynchronous command/response interface with additional service related information. It is used to transfer a system service command from the fabric to the System Controller and to transfer status back from the System Controller to the fabric.
The System Service interface operates in conjunction with the mailbox interface, which is a synchronous interface operating on a user-supplied clock. The mailbox interface is used for passing data related to the system service between the fabric and the System Controller (in both directions). This interface consists of a set of address, data, and control signals for a 2kB dual-port RAM within the System Controller.
- Supports Device and Data System Services
- Supports fabric services
- Supports AMBA interface to Perform System services
- Supports APB slave interface for access to System Service related registers
- Support for Flash Freeze service through AMBA (APB) and non-AMBA interface
