Interrupt vector table is generated by Processor Expert into the Vectors.c file. Because MQX Lite implements its own interrupt management, _int_kernel_isr() the interrupt routine is installed to the interrupt vector table by default. On Kinetis platforms with ARM® Cortex®-M0+ code, the first fifteen interrupt vectors are not managed by MQX Lite and Processor Expert installs its own default <CpuComponentName> _Interrupt() interrupt service routine to these interrupt vectors.
