This can be utilized by external hosts or C64x+ megamodules to generate interrupts to other DSPs. A write of 1 to the IPCG field of IPCGRn register generates an interrupt pulse to C64x+ Megamodulen (n = 0-5). These registers also provide a source ID, by which up to 28 different sources of interrupts can be identified. 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 SRCS27 SRCS26 SRCS25 SRCS24 SRCS23 SRCS22 SRCS21 SRCS20 SRCS19 SRCS18 SRCS17 SRCS16 SRCS15 SRCS14 SRCS13 SRCS12 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 15 14 13 12 11 10 9 8 7 6 5 4 3 1 0 SRCS11 SRCS10 SRCS9 SRCS8 SRCS7 SRCS6 SRCS5 SRCS4 SRCS3 SRCS2 SRCS1 SRCS0 Reserved IPCG R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R-000 R/W-0 LEGEND: R/W = Read/Write; R = Read only; -n = value after reset Figure 3-9.
