/**
* @ingroup los_config
* Configuration item for using system defined vector base address and interrupt handlers.
* If LOSCFG_USE_SYSTEM_DEFINED_INTERRUPT is set to 0, vector base address will not be
* modified by system. In arm, it should be noted that PendSV_Handler and SysTick_Handler should
* be redefined to HalPendSV and OsTickHandler respectably in this case, because system depends on
* these interrupt handlers to run normally. What's more, LOS_HwiCreate will not register handler.
