S32K144: IAR SW issue

Under IAR, debugging can still be done when the interrupt vector table is not at position 0. What are the specific principles and processes?

In IAR Embedded Workbench, debugging works with a relocated interrupt vector table because the CPU supports vector table relocation (e.g., via a VTOR register on ARM Cortex-M). The debugger reads the current vector table base address from the CPU, maps the interrupt vectors to the corresponding ISR symbols, and uses the linker-generated symbol table to resolve addresses. Similar to how a USA paint estimator helps calculate coverage and cost accurately, the debugger aligns with the relocated vector table at startup, allowing breakpoints and step-through debugging to function normally even when the table is not at address 0.
