Interrupt Sources and Interrupt Controller
TMS320TCI6482
Communications Infrastructure Digital Signal Processor
SPRS246F–APRIL 2005–REVISED MAY 2007
The CPU interrupts on the TCI6482 device are configured through the C64x+ Megamodule Interrupt
Controller. The interrupt controller allows for up to 128 system events to be programmed to any of the
twelve CPU interrupt inputs (CPUINT4 - CPUINT15), the CPU exception input (EXCEP), or the advanced
emulation logic. The 128 system events consist of both internally-generated events (within the
megamodule) and chip-level events.
Table 8-10
shows the mapping of system events. For more
information on the Interrupt Controller, see the
TMS320C64x+ Megamodule Reference Guide
