Hello,
I am working in c6748 lcdk kit. I have doubts about what is INT0,INT1,INT2,INT3 in c6748. From 
I understood from INT4 to INT15 is user configurable and priority decrease. What is INT0-INT3 used for if they are not user mappable? Where are they used in program?
With Regards
Shalini
Hi Shalini,
INT0 is the reset interrupt, corresponding to the RESET signal, and has the highest priority. INT1 is the nonmaskable interrupt (NMI), corresponding to the NMI signal and has the second highest priority. INT2/3 are reserved and not used.
