** User clock definitions can be done for the following clock settings: | |
** - CLOCK_SETUP : Execute the clock settings form the settings below in | |
** SystemInit() | |
** - __CLKMO : External clock frequency for main oscillion | |
** - __CLKSO : External clock frequency for sub oscillion | |
** - SCM_CTL : System Clock Mode Control Register | |
** - BSC_PSR : Base Clock Prescaler Register | |
** - APBC0_PSR : APB0 Prescaler Register | |
** - APBC1_PSR : APB1 Prescaler Register | |
** - APBC2_PSR : APB2 Prescaler Register | |
** - SWC_PSR : Software Watchdog Clock Prescaler Register | |
** - TTC_PSR : Trace Clock Prescaler Register | |
** - CSW_TMR : Clock Stabilization Wait Time Register | |
** - PSW_TMR : PLL Clock Stabilization Wait Time Setup Register | |
** - PLL_CTL1 : PLL Control Register 1 | |
** - PLL_CTL2 : PLL Control Register 2 | |
** | |
** The register settings are check for correct values of reserved bits. | |
** Otherwise a preprocessor error is output and stops the build process. | |
** Furthermore the 'master clock' is retrieved from the register settings | |
** and the system clock (HCLK) is calculated from the Base Clock Prescaler | |
** Register (BSC_PSR). This value is used for the global CMSIS variable | |
** #SystemCoreClock. Also the absolute external, PLL and HCL freqeuncy is | |
** is checked. Note that not all possible wrong setting are checked! The | |
** user has to take care to fulfill the settings stated in the according | |
** device's data sheet! | |
** | |
** User definition for Hardware Watchdog: | |
** - HWWD_DISABLE : Disables Hardware Watchdog in SystemInit() | |
** | |
** User definition for CR Trimming: | |
** - CR_TRIM_SETUP : Enables CR trimming in SystemInit() | |
