+ * @brief RCC HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Reset and Clock Control (RCC) peripheral:
+ * + Initialization and de-initialization functions
+ * + Peripheral Control functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### RCC specific features #####
+ ==============================================================================
+ [..]
+ After reset the device is running from Internal High Speed oscillator
+ (HSI 64MHz) with Flash 0 wait state,and all peripherals are off except
+ internal SRAM, Flash, JTAG and PWR
+ (+) There is no pre-scaler on High speed (AHB) and Low speed (APB) buses;
+ all peripherals mapped on these buses are running at HSI speed.
+ (+) The clock for all peripherals is switched off, except the SRAM and FLASH.
+ (+) All GPIOs are in analogue mode , except the JTAG pins which
+ are assigned to be used for debug purpose.
+
+ [..]
+ Once the device started from reset, the user application has to:
+ (+) Configure the clock source to be used to drive the System clock
+ (if the application needs higher frequency/performance)
+ (+) Configure the System clock frequency and Flash settings
+ (+) Configure the AHB and APB buses pre-scalers
+ (+) Enable the clock for the peripheral(s) to be used
+ (+) Configure the clock kernel source(s) for peripherals which clocks are not
+ derived from the System clock through :RCC_D1CCIPR,RCC_D2CCIP1R,RCC_D2CCIP2R
+ and RCC_D3CCIPR registers
+
+ ##### RCC Limitations #####
+ ==============================================================================
+ [..]
+ A delay between an RCC peripheral clock enable and the effective peripheral
+ enabling should be taken into account in order to manage the peripheral read/write
+ from/to registers.
+ (+) This delay depends on the peripheral mapping.
+ (+) If peripheral is mapped on AHB: the delay is 2 AHB clock cycle
+ after the clock enable bit is set on the hardware register
+ (+) If peripheral is mapped on APB: the delay is 2 APB clock cycle
+ after the clock enable bit is set on the hardware register
+
+ [..]
+ Implemented Workaround:
+ (+) For AHB & APB peripherals, a dummy read to the peripheral register has been
+ inserted in each __HAL_RCC_PPP_CLK_ENABLE() macro.

+ [..]
+ This section provides functions allowing to configure the internal/external oscillators
+ (HSE, HSI, LSE,CSI, LSI,HSI48, PLL, CSS and MCO) and the System buses clocks (SYSCLK, AHB3, AHB1
+ AHB2,AHB4,APB3, APB1L, APB1H, APB2, and APB4).
+
+ [..] Internal/external clock and PLL configuration
+ (#) HSI (high-speed internal), 64 MHz factory-trimmed RC used directly or through
+ the PLL as System clock source.
+ (#) CSI is a low-power RC oscillator which can be used directly as system clock, peripheral
+ clock, or PLL input.But even with frequency calibration, is less accurate than an
+ external crystal oscillator or ceramic resonator.
+ (#) LSI (low-speed internal), 32 KHz low consumption RC used as IWDG and/or RTC
+ clock source.
+
+ (#) HSE (high-speed external), 4 to 48 MHz crystal oscillator used directly or
+ through the PLL as System clock source. Can be used also as RTC clock source.
+
+ (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.
+
+ (#) PLL , The RCC features three independent PLLs (clocked by HSI , HSE or CSI),
+ featuring three different output clocks and able to work either in integer or Fractional mode.
+ (++) A main PLL, PLL1, which is generally used to provide clocks to the CPU
+ and to some peripherals.
+ (++) Two dedicated PLLs, PLL2 and PLL3, which are used to generate the kernel clock for peripherals.
+
+
+ (#) CSS (Clock security system), once enabled and if a HSE clock failure occurs
+ (HSE used directly or through PLL as System clock source), the System clock
+ is automatically switched to HSI and an interrupt is generated if enabled.
+ The interrupt is linked to the Cortex-M NMI (Non-Mask-able Interrupt)
+ exception vector.
+
+ (#) MCO1 (micro controller clock output), used to output HSI, LSE, HSE, PLL1(PLL1_Q)
+ or HSI48 clock (through a configurable pre-scaler) on PA8 pin.
+
+ (#) MCO2 (micro controller clock output), used to output HSE, PLL2(PLL2_P), SYSCLK,
+ LSI, CSI, or PLL1(PLL1_P) clock (through a configurable pre-scaler) on PC9 pin.
+
+ [..] System, AHB and APB buses clocks configuration
+ (#) Several clock sources can be used to drive the System clock (SYSCLK): CSI,HSI,
+ HSE and PLL.
+ The AHB clock (HCLK) is derived from System core clock through configurable
+ pre-scaler and used to clock the CPU, memory and peripherals mapped
+ on AHB and APB bus of the 3 Domains (D1, D2, D3)* through configurable pre-scalers
+ and used to clock the peripherals mapped on these buses. You can use
+ "HAL_RCC_GetSysClockFreq()" function to retrieve system clock frequency.
+
+ -@- All the peripheral clocks are derived from the System clock (SYSCLK) except those
+ with dual clock domain where kernel source clock could be selected through
+ RCC_D1CCIPR,RCC_D2CCIP1R,RCC_D2CCIP2R and RCC_D3CCIPR registers.
+
+ (*) : 2 Domains (CD and SRD) for stm32h7a3xx and stm32h7b3xx family lines.
