Parameters

vectTab	specifies if the vector table is in RAM or FLASH memory This parameter can be one of the following values: NVIC_VECT_TAB_RAM : NVIC vector table base address launch from RAM NVIC_VECT_TAB_FLASH : NVIC vector table base address launch from flash
Offset	Vector Table base offset field. This value must be a multiple of 0x200

Return values

None
