Information on internal exceptions

ANUJ AGARWAL

I am implementing internal exception handling for TI DSP 6618. Is any documentation and reference available for the same?

In particular I am looking for the event ID in case of illegal opcodes.

Hi Anuj,

I guess the section 2.9.6 Internal Exception Report Register (IERR) of SPRUGH7 (http://www.ti.com/lit/ug/sprugh7/sprugh7.pdf) is which you wanted. My understanding is, bit 3 (OPX) is set when illegal opcode is fetched.

In addition, Chapter 7 CPU Exceptions of the document covers big picture of exception handing by hardware.

Atsushi
