Summary
Internal High Speed oscillator (HSI) value. This value is used by the RCC HAL module to compute the system frequency (when HSI is used as system clock source, directly or through the PLL). Value of the Internal oscillator in Hz
Default value of the External oscillator in Hz
Miscellaneous Configuration *********************** Vector Table base offset field. This value must be a multiple of 0x200.
