Macro Definition Documentation

#define FSL_CLOCK_DRIVER_VERSION (MAKE_VERSION(2, 3, 7))

#define FSL_SDK_DISABLE_DRIVER_CLOCK_CONTROL 0

When set to 0, peripheral drivers will enable clock in initialize function and disable clock in de-initialize function. When set to 1, peripheral driver will not control the clock, application could control the clock out of the driver.

Note: All drivers share this feature switcher. If it is set to 1, application should handle clock enable and disable for all drivers.

#define PLL_CONFIGFLAG_USEINRATE (1U << 0U)

When the PLL_CONFIGFLAG_USEINRATE flag is selected, the 'InputRate' field in the configuration structure must be assigned with the expected PLL frequency. If the PLL_CONFIGFLAG_USEINRATE is not used, 'InputRate' is ignored in the configuration function and the driver will determine the PLL rate from the currently selected PLL source. This flag might be used to configure the PLL input clock more accurately when using the WDT oscillator or a more dyanmic CLKIN source.

When the PLL_CONFIGFLAG_FORCENOFRACT flag is selected, the PLL hardware for the automatic bandwidth selection, Spread Spectrum (SS) support, and fractional M-divider are not used.
Flag to use InputRate in PLL configuration structure for setup

#define PLL_SETUPFLAG_POWERUP (1U << 0U)

Setup will power on the PLL after setup

Returns: PLL0 output clock rate the setup structure will generate

pll_error_t CLOCK_SetupPLL0Data	(	pll_config_t *	pControl,
		pll_setup_t *	pSetup
	)

Parameters

pControl	: Pointer to populated PLL control structure to generate setup with
pSetup	: Pointer to PLL setup structure to be filled

Returns: PLL_ERROR_SUCCESS on success, or PLL setup error code

Note: Actual frequency for setup may vary from the desired frequency based on the accuracy of input clocks, rounding, non-fractional PLL mode, etc.

pll_error_t CLOCK_SetupPLL0Prec	(	pll_setup_t *	pSetup,
		uint32_t	flagcfg
	)

Parameters

pSetup	: Pointer to populated PLL setup structure
flagcfg	: Flag configuration for PLL config structure

Returns: PLL_ERROR_SUCCESS on success, or PLL setup error code

Note: This function will power off the PLL, setup the PLL with the new setup data, and then optionally powerup the PLL, wait for PLL lock, and adjust system voltages to the new PLL rate. The function will not alter any source clocks (ie, main systen clock) that may use the PLL, so these should be setup prior to and after exiting the function.

pll_error_t CLOCK_SetPLL0Freq ( const pll_setup_t * pSetup )

Parameters

pSetup : Pointer to populated PLL setup structure

Returns: kStatus_PLL_Success on success, or PLL setup error code

Note: This function will power off the PLL, setup the PLL with the new setup data, and then optionally powerup the PLL, wait for PLL lock, and adjust system voltages to the new PLL rate. The function will not alter any source clocks (ie, main systen clock) that may use the PLL, so these should be setup prior to and after exiting the function.

pll_error_t CLOCK_SetPLL1Freq ( const pll_setup_t * pSetup )

Parameters

pSetup : Pointer to populated PLL setup structure

Returns: kStatus_PLL_Success on success, or PLL setup error code

Note: This function will power off the PLL, setup the PLL with the new setup data, and then optionally powerup the PLL, wait for PLL lock, and adjust system voltages to the new PLL rate. The function will not alter any source clocks (ie, main systen clock) that may use the PLL, so these should be setup prior to and after exiting the function.

void CLOCK_SetupPLL0Mult	(	uint32_t	multiply_by,
		uint32_t	input_freq
	)

Parameters

multiply_by	: multiplier
input_freq	: Clock input frequency of the PLL

Returns: Nothing

Note: Unlike the Chip_Clock_SetupSystemPLLPrec() function, this function does not disable or enable PLL power, wait for PLL lock, or adjust system voltages. These must be done in the application. The function will not alter any source clocks (ie, main systen clock) that may use the PLL, so these should be setup prior to and after exiting the function.
