27; The modules in this file are included in the libraries, and may be replaced
28; by any user-defined modules that define the PUBLIC symbol _program_start or
29; a user defined start symbol.
30; To override the cstartup defined in the library, simply add your modified
31; version to the workbench project.
32;
33; The vector table is normally located at address 0.
34; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.
35; The name "__vector_table" has special meaning for C-SPY:
36; it is where the SP start value is found, and the NVIC vector
37; table register (VTOR) is initialized to this address if != 0.
