Interrupt vector table data

[SSK]

Hello forum members,

I am using Codewarrior 4.6 build 6350 for MC9S12A128.

Where can I find the interrupt vector table data for HCS12?

Out of 64 vectors, where can I find which vector is assigned to which ISR?

Is there any rule for this assignment?

I am using ISR for SCI0 at vector 20, where can I assign ISR for SCI1? Whether it should be at vector 21?

Any document regarding this will be highly appreciated.

Thanks in advance.

The interrupt table is located in the device guide for your microncontroller.  It can be found here:
