10.8.2 Vector-Offset Initialization Module

The vector-offset initialization module (device_voff_init.S in the DFP you have downloaded for your project), which is compiled when linking your application, uses the __vector_offset_n symbols defined in the default linker script. The value of each symbol is the offset of the vector’s address from the ebase register’s address. The vector-offset initialization module, uses the symbol value to create a .data section using the address of the corresponding OFFxxx special function register. This means that the standard linker-generated data-initialization template contains the values used to initialize the OFFxxx registers.
