I'm seeing interrupt Viinstr trigger, but I'm not sure why. Can someone please tell me about this interrupt?

Also, Where can I get a detailed list telling me about all the available interrupts?

IDE: CW 10.1

For information on the MCF51CN128RM's interrupt vector table, download the CPU's reference manual from here. Table 5-1 of this document shows the interrupt vector table for the MCF51CN128 series parts.

Thanks for the link.

Unfortunatly, I was unable to find "Viinstr" anywhere in that document.

Hello

According to file mcf51cn128.h, Viinstr is associated with vector number 4 (#define VectorNumber_Viinstr 4U).

According to the table 5-3. ColdFire Exception Vector Table MCF51CN128 reference manual J2MEJediMaster was referencing earlier the exception associated with vector number 4 is Illegal instruction.

So you are chaining an Illegal instruction exception here.
