NAVSS0_INTR_AGGR0 supports the following features:
- 64-bit VBUSP slave using 64-bit registers
- Provides a set of TI Interrupt Architecture compliant interrupt status and mask registers which are used to pass specific event status to one or more host blocks.
- Maps a collection of "DMA Messaged Events" which are input through an Event Transport Lane (ETL) into specific bit locations in one or more interrupt cause registers
- Mapping is performed based on a programmable table which provides a single location for each ordinal input event number (0 through sevt_cnt-1)
- Table specifies a specific bit in a specific cause register that the event should set or clear depending on the type of event (up vs down)
- Tracks a single 'event up'/'event down' condition. There is no event counting. (The 'cnt' field of the ETL is ignored)
- Tracked status interrupts are presented to the user through a standard interrupt register interface
- Provides separate 'enable set' and 'enable clear' registers
- Provides both masked and unmasked interrupt status
- Interrupt status bits can be manually cleared using 'write 1 to clear'
- Provides a set of Global Event Input (GEVI) counters which can count events which were delivered via an ingress Event Transport Lane (ETL)
- Each counted event provides an register by which the count can be read and an register by which a specified amount can be decremented by the host
- Each counted event generates a egress Global event on a zero to non-zero and non-zero to zero transition, controllable through a mapping register
- Provides a set of Local Event Input (LEVI) to Global event registers which can be used to convert pulsed discrete interrupt inputs or clock synchronous rising edge events into Global events on an egress ETL
- Each ingress event index provides a configurable 'pulse' or 'rising edge' bit, plus the configurable index of the generated Global event
- Provides a set of Global Event Input (GEVI) 'Multicast' registers which can take a Global event from an ingress ETL and generate two egress Global events on two egress ETL interfaces.
