Macros
#define	CY_SYSCLK_DRV_VERSION_MAJOR   3
	Driver major version.
#define	CY_SYSCLK_DRV_VERSION_MINOR   100
	Driver minor version.
#define	CY_SYSCLK_ID   CY_PDL_DRV_ID(0x12U)
	Sysclk driver identifier.
#define	CY_SYSCLK_ILO_FREQ   (32768UL) /* Hz */
	ILO clock frequency.
#define	CY_SYSCLK_WCO_FREQ   (32768UL) /* Hz */
	WCO clock frequency.
#define	CY_SYSCLK_PILO_FREQ   (32768UL) /* Hz */
	PILO clock frequency.
#define	CY_SYSCLK_IMO_FREQ   (8000000UL) /* Hz */
	IMO clock frequency.
#define	CY_SYSCLK_MFO_FREQ   (2000000UL) /* Hz */
