 * The function _system_pre_init it called by the start-up code before
 * "main" is called, and before data segment initialization is
 * performed.
 *
 * This is a template file, modify to perform any initialization that
 * should take place early.
 *
 * The return value of this function controls if data segment
 * initialization should take place. If 0 is returned, it is bypassed.
 *
 * For the MSP430 microcontroller family, please consider disabling
 * the watchdog timer here, as it could time-out during the data
 * segment initialization.
