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
The assert_param macro is used for function's parameters check.
Miscellaneous Configuration *********************** Vector Table base offset field. This value must be a multiple of 0x200.

Palette Description The following are the entries of the palette table. The entries are stored as a 32-bit values of which 24 bits are actually used according to the following bit mask: 0xBBGGRR The lower 8 bits represent the Red component. The middle 8 bits represent the Green component. The highest 8 bits represent the Blue component.
