IPCARx are the IPC interrupt-acknowledgement registers to facilitate inter-CorePac core interrupts.
The C6657 has two IPCARx registers (IPCAR0 and IPCAR1) while the C6655 has only IPCAR0. These registers also provide a Source ID facility by which up to 28 different sources of interrupts can be identified. Allocation of source bits to source processor and meaning is entirely based on software convention. The register field descriptions are shown in the following tables. Virtually anything can be a source for these registers as this is completely controlled by software. Any master that has access to BOOTCFG module space can write to these registers. The IPC Acknowledgement Register is shown in Figure 8-12 and described in Table 8-14.
