The interface signals can be grouped into the following four categories:
- The clock and reset signals (see Section 30.2, VCP Integration for signal mapping).
- The register interface that is used for the connection with the L4 interconnect for configuration and data transfer through L3_MAIN.
- The EDMA and interrupt interface used to request new context and packet data or to indicate available result data.
- Slave idle protocol to PRCM.
