- * @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 8MHz) with Flash 0 wait state, Flash prefetch buffer is enabled,
- and all peripherals are off except internal SRAM, Flash and JTAG.
- (+) There is no prescaler 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 input floating state, 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 prescalers
- (+) Enable the clock for the peripheral(s) to be used
- (+) Configure the clock source(s) for peripherals whose clocks are not
- derived from the System clock (RTC, ADC, I2C, USART, TIM, USB FS, etc..)
-
- ##### 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.
- (++) AHB & APB peripherals, 1 dummy read is necessary
-
- [..]
- Workarounds:
- (#) 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, HSI14, HSI48, LSE, LSI, PLL, CSS and MCO) and the System buses clocks (SYSCLK,
- AHB and APB1).
-
- [..] Internal/external clock and PLL configuration
- (#) HSI (high-speed internal), 8 MHz factory-trimmed RC used directly or through
- the PLL as System clock source.
- The HSI clock can be used also to clock the USART and I2C peripherals.
-
- (#) HSI14 (high-speed internal), 14 MHz factory-trimmed RC used directly to clock
- the ADC peripheral.
-
- (#) LSI (low-speed internal), ~40 KHz low consumption RC used as IWDG and/or RTC
- clock source.
-
- (#) HSE (high-speed external), 4 to 32 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 (clocked by HSI, HSI48 or HSE), featuring different output clocks:
- (++) The first output is used to generate the high speed system clock (up to 48 MHz)
- (++) The second output is used to generate the clock for the USB FS (48 MHz)
- (++) The third output may be used to generate the clock for the TIM, I2C and USART
- peripherals (up to 48 MHz)
-
- (#) CSS (Clock security system), once enable using the macro __HAL_RCC_CSS_ENABLE()
- and if a HSE clock failure occurs(HSE used directly or through PLL as System
- clock source), the System clocks automatically switched to HSI and an interrupt
- is generated if enabled. The interrupt is linked to the Cortex-M0 NMI
- (Non-Maskable Interrupt) exception vector.
-
- (#) MCO (microcontroller clock output), used to output SYSCLK, HSI, HSE, LSI, LSE or PLL
- clock (divided by 2) output on pin (such as PA8 pin).
-
- [..] System, AHB and APB buses clocks configuration
- (#) Several clock sources can be used to drive the System clock (SYSCLK): HSI,
- HSE and PLL.
- The AHB clock (HCLK) is derived from System clock through configurable
- prescaler and used to clock the CPU, memory and peripherals mapped
- on AHB bus (DMA, GPIO...). APB1 (PCLK1) clock is derived
- from AHB clock through configurable prescalers and used to clock
- the peripherals mapped on these buses. You can use
- "@ref HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.
-
- (#) All the peripheral clocks are derived from the System clock (SYSCLK) except:
- (++) The FLASH program/erase clock which is always HSI 8MHz clock.
- (++) The USB 48 MHz clock which is derived from the PLL VCO clock.
- (++) The USART clock which can be derived as well from HSI 8MHz, LSI or LSE.
- (++) The I2C clock which can be derived as well from HSI 8MHz clock.
- (++) The ADC clock which is derived from PLL output.
- (++) The RTC clock which is derived from the LSE, LSI or 1 MHz HSE_RTC
- (HSE divided by a programmable prescaler). The System clock (SYSCLK)
- frequency must be higher or equal to the RTC clock frequency.
- (++) IWDG clock which is always the LSI clock.
-
- (#) For the STM32F0xx devices, the maximum frequency of the SYSCLK, HCLK and PCLK1 is 48 MHz,
- Depending on the SYSCLK frequency, the flash latency should be adapted accordingly.
-
- (#) After reset, the System clock source is the HSI (8 MHz) with 0 WS and
- prefetch is disabled.
