Description
Reads return current value of internal register bit.
Writes:
0 = No effect
1 = Sets both SRCSx and the corresponding SRCCx.
Reserved
Reads return 0.
Writes:
0 = No effect
1 = Creates an inter-DSP/ARM interrupt.
8.2.3.13 IPC Acknowledgement (IPCARx) Registers
The IPCARx registers facilitate inter-CorePac interrupt acknowledgement.
The TCI6636K2H has twelve IPCARx (IPCAR0 through IPCAR11) 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 Acknowledgement
Register is shown in the following figure and table.

8.2.3.14 IPC Generation Host (IPCGRH) Register
The IPCGRH register facilitates interrupts to external hosts. Operation and use of the IPCGRH register is the same
as for other IPCGR registers. The interrupt output pulse created by the IPCGRH register appears on device pin
HOUT.
