Description: This function initializes the clock as defined by the MHC and Clock Manager selections. The function will configure the NVM Flash Wait states based on the configured CPU operational frequency. It will then configure the oscillators. For each of the clock sources (External Oscillator, Digital Phase Locked Loop, Internal 48MHz Oscillator, External 32KHz oscillator and the Internal 32KHz oscillator) enabled in MHC, the function will configure the clock settings and will then wait till the clock is ready. In case of DPLL, the function will wait till a lock is obtained. The function will then configure the Generic clock generators based on MHC configurations. If a Generic Clock is enabled in MHC, this will be enabled in the CLOCK_Initialize() function. The function will apply the CPU clock divider and will wait for the Main Clock module to get ready. If the Main Clock to the Peripheral APB and AHB interfaces was enabled in MHC, these will be enabled in the CLOCK_Initialize() function. If the Peripheral Clock Channels were enabled in MHC, these will be enabled in the CLOCK_Initialize() function. The peripheral AHB and APB main clock and peripheral channel clocks will be enabled when the peripheral specific initialize functions are called. This will override the setting in MHC. The Generic Clock Generator source for desired peripheral channel must be configured in MHC. Precondition: MHC GUI should be configured with the right values. Incorrect configuration of the Clock will result in incorrect peripheral behavior or a non functional device. Parameters: None. Returns: None. Example: CLOCK_Initialize(); Remarks: This function should be called before calling other Clock library functions. */ void CLOCK_Initialize (void); #ifdef __cplusplus // Provide C++ Compatibility } #endif #endif /* PLIB_CLOCK_H */
