Function Documentation

Cy_SysClk_ImoSetFrequency()

cy_en_sysclk_status_t Cy_SysClk_ImoSetFrequency

(

cy_en_sysclk_imo_freq_t

freq

)

Sets the IMO desired frequency.

Note

There is a Cy_SysClk_ImoLock feature to improve an IMO precision.

Parameters

freq	- the desired IMO frequency, cy_en_sysclk_imo_freq_t.

Note

Call SystemCoreClockUpdate after this function calling if it affects the ClkSys frequency.

Call Cy_SysLib_SetWaitStates before calling this function if ClkSys frequency is increasing.

Call Cy_SysLib_SetWaitStates after calling this function if ClkSys frequency is decreasing.

Returns

Error / status code cy_en_sysclk_status_t :
CY_SYSCLK_SUCCESS - the frequency is set as requested
CY_SYSCLK_BAD_PARAM - Invalid parameter. CY_SYSCLK_INVALID_STATE - IMO is not enabled.

Cy_SysClk_ImoGetFrequency()

uint32_t Cy_SysClk_ImoGetFrequency

(

void

)

Returns the IMO nominal frequency.

Returns

the frequency value in Hz.

Cy_SysClk_ImoLock()

cy_en_sysclk_status_t Cy_SysClk_ImoLock

(

cy_en_sysclk_imo_lock_t

lock

)

Locks/unlocks IMO.

Parameters

lock	- the desired IMO lock state, cy_en_sysclk_imo_lock_t

Returns

Error / status code cy_en_sysclk_status_t :
CY_SYSCLK_SUCCESS - the lock state is set as requested
CY_SYSCLK_BAD_PARAM - Invalid parameter
CY_SYSCLK_INVALID_STATE - Invalid state (IMO or WCO is not enabled, etc.)

Cy_SysClk_ImoGetLockStatus()

cy_en_sysclk_imo_lock_t Cy_SysClk_ImoGetLockStatus

(

void

)

Returns IMO lock status.

Returns

IMO lock state cy_en_sysclk_imo_lock_t.
