    CAN interrupt configuration for TC397 StepB MCU

    I have a question regarding how to select the interrupt address/vector for a specific CAN Node in the MCU

    Example i am using CAN00 and CAN01 because of my hardware configuration.

    Each CAN node has 16 interrupt lines:-
    SRC_CANzINT0
    SRC_CANzINT1
    ....
    ....
    ...
    SRC_CANzINT15

    z=0,1 and 2

    which one do i select for my CAN nodes?

    I found it.

    It depends on which CAN module and CAN node you are using.

    If you are using CAN module "x" and CAN node "y"
    then you need to use SRC_CANxINTy

    So, if you use CAN module 0 Node 0, you need to use SRC_CAN0INT0 address in your config tool.

    Actually there are 16 interrupt lines per module - not per node. I made the same assumption until my debugger proved otherwise. See my post from Aug 6.
