WebThe base address of the vector table is initialized to the boot address (must be aligned to 256 bytes, i.e., its least significant byte must be 0x00) when the core is booting. The base address can be changed after bootup by writing to the mtvec CSR. For more information, see the Control and Status Registers documentation.
