These registers also provide a Source ID facility identifying up to 28 different sources of interrupts.
Allocation of source bits to source processor and meaning is entirely based on software convention. The
register field descriptions are given in the following tables. There can be numerous sources 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 Generation Register is shown in Figure 9-27 and described in
Table 9-43.

Bit Field Description
31-4 SRCSx Reads return current value of internal register bit.
Writes:
• 0 = No effect
• 1 = Sets both SRCSx and the corresponding SRCCx.
3-1 Reserved Reserved
0 IPCG Reads return 0.
Writes:
• 0 = No effect
• 1 = Creates an inter-DSP interrupt.
9.2.3.16 IPC Acknowledgment (IPCARx) Registers
The IPCARx registers facilitate inter-CorePac interrupt acknowledgment.
The 66AK2L06 device has six IPCARx registers. 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 given
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 Acknowledgment Register is shown in the following figure and table.
