;	Interrupt Service Table (IST)
; 
; This is a table of Interrupt Service Fetch Packets (ISFP) which
; contain code for servicing the interrupts.
; This serves as a multi-purpose example for the C6x family.
; Consult the TI DSP Reference manual to determine which interrupts 
; apply to a given target and/or application.
; The IST consists of 16 consecutive fetch ISFPs.
* Each ISFP contains 8 32-bit instructions, or 32bytes of code.
