Cy_SysClk_HposcEnable()

__STATIC_INLINE void Cy_SysClk_HposcEnable

(

void

)

Enables the HPOSC.

Note

Applicable to PSOC4 HVMS/PA only.

Function Usage

        /* Scenario: The HFCLK needs to be sourced by the HPOSC instead of the IMO. */

        /* Enable the HPOSC */
        Cy_SysClk_HposcEnable();

        /* Now switch the HFCLK source to HPOSC */
        Cy_SysClk_ClkHfSetSource(CY_SYSCLK_CLKHF_IN_HPOSC);

        /* Disable the IMO */
        Cy_SysClk_ImoDisable();

Cy_SysClk_HposcIsEnabled()

__STATIC_INLINE bool Cy_SysClk_HposcIsEnabled

(

void

)

Returns the HPOSC enable/disable state.

Note

Applicable to PSOC4 HVMS/PA only.

Function Usage

        /* Scenario: HPOSC is not needed - shut it down to reduce power consumption. */

        if (Cy_SysClk_HposcIsEnabled())
        {
            Cy_SysClk_HposcDisable(); /* Disable the HPOSC */
        }

Cy_SysClk_HposcDisable()

__STATIC_INLINE cy_en_sysclk_status_t Cy_SysClk_HposcDisable

(

void

)

Disables the HPOSC.

HPOSC can't be disabled if the HPOSC is selected as a HFCLK source.

Returns

Error / status code, cy_en_sysclk_status_t :
CY_SYSCLK_SUCCESS - HPOSC successfully disabled
CY_SYSCLK_INVALID_STATE - Cannot disable the HPOSC if selected as the HFCLK source.

Note

Applicable to PSOC4 HVMS/PA only.

Function Usage

        /* Scenario: HPOSC is not needed - shut it down to reduce power consumption. */

        if (Cy_SysClk_HposcIsEnabled())
        {
            Cy_SysClk_HposcDisable(); /* Disable the HPOSC */
        }
