29 / 110 page ![]() DocID025763 Rev 1 29/110 PM0223 The STM32L0 Cortex-M0+ Processor 35 2.3.4 Vector table The vector table contains the reset value of the stack pointer, and the start addresses, also called exception vectors, for all exception handlers. Figure 7 on page 29 shows the order of the exception vectors in the vector table. The least-significant bit of each vector must be 1, indicating that the exception handler is written in Thumb code. Figure 7. Vector table On system reset, the vector table is fixed at address 0x00000000. Privileged software can write to the VTOR to relocate the vector table start address to a different memory location, in the range 0x00000000 to 0xFFFFFF80 in multiples of 256 bytes, see Vector Table Offset Register on page 4-11. |
