| ; The vector table is normally located at address 0. | |
| ; When debugging in RAM, it can be located in RAM, aligned to at least 2^6. | |
| ; The name "__vector_table" has special meaning for C-SPY: | |
| ; it is where the SP start value is found, and the NVIC vector | |
| ; table register (VTOR) is initialized to this address if != 0. | |
