Detailed Description

Function Documentation

Cy_SysClk_GetInterruptStatus()

__STATIC_INLINE uint32_t Cy_SysClk_GetInterruptStatus

(

void

)

Returns the interrupt status.

This API is available only for PSoC 4500S and 4100S Max devices.

Returns

The interrupt status, see Interrupt Masks :

• CY_SYSCLK_INTR_PLL_LOCK
• CY_SYSCLK_INTR_WD_ERR
• CY_SYSCLK_INTR_SW_IMO

Cy_SysClk_GetInterruptStatusMasked()

__STATIC_INLINE uint32_t Cy_SysClk_GetInterruptStatusMasked

(

void

)

Returns the logical AND of the corresponding INTR and INTR_MASK registers in a single-load operation.

This API is available only for PSoC 4500S and 4100S Max devices.

Returns

The masked interrupt status, see Interrupt Masks :

• CY_SYSCLK_INTR_PLL_LOCK
• CY_SYSCLK_INTR_WD_ERR
• CY_SYSCLK_INTR_SW_IMO

Function Usage

uint32_t csvIntr = 0UL;

void Csv_Isr(void)
{
    csvIntr = Cy_SysClk_GetInterruptStatusMasked();
    Cy_SysClk_ClearInterrupt(csvIntr);
}

Cy_SysClk_ClearInterrupt()

__STATIC_INLINE void Cy_SysClk_ClearInterrupt

(

uint32_t

intrMask

)

Clears the interrupt status.

This API is available only for PSoC 4500S and 4100S Max devices.

Parameters

intrMask

The mask of interrupts to clear. Typically this is the value returned by Cy_SysClk_GetInterruptStatusMasked or Cy_SysClk_GetInterruptStatus. Alternately, select one or more values from Interrupt Masks and "OR" them together. CY_SYSCLK_INTR_PLL_LOCK CY_SYSCLK_INTR_WD_ERR CY_SYSCLK_INTR_SW_IMO

Function Usage

uint32_t csvIntr = 0UL;

void Csv_Isr(void)
{
    csvIntr = Cy_SysClk_GetInterruptStatusMasked();
    Cy_SysClk_ClearInterrupt(csvIntr);
}

Cy_SysClk_SetInterrupt()

__STATIC_INLINE void Cy_SysClk_SetInterrupt

(

uint32_t

intrMask

)

Sets the specified interrupt status.

Intended mostly for debugging.

This API is available only for PSoC 4500S and 4100S Max devices.

Parameters

intrMask

The mask of interrupts to set. Select one or more values from Interrupt Masks and "OR" them together. CY_SYSCLK_INTR_PLL_LOCK CY_SYSCLK_INTR_WD_ERR CY_SYSCLK_INTR_SW_IMO

Cy_SysClk_GetInterruptMask()

__STATIC_INLINE uint32_t Cy_SysClk_GetInterruptMask

(

void

)

Returns the interrupt mask value.

This API is available only for PSoC 4500S and 4100S Max devices.

Returns

The interrupt mask value, see Interrupt Masks :

• CY_SYSCLK_INTR_PLL_LOCK
• CY_SYSCLK_INTR_WD_ERR
• CY_SYSCLK_INTR_SW_IMO

Function Usage

    /* Scenario: Check whether a specific interrupt source is enabled. */
    uint32_t intrMask = Cy_SysClk_GetInterruptMask();
    
    if (CY_SYSCLK_INTR_PLL_LOCK == (intrMask & CY_SYSCLK_INTR_PLL_LOCK))
    {
        /* The PLL unlock interrupt was enabled. */
    }

Cy_SysClk_SetInterruptMask()

__STATIC_INLINE void Cy_SysClk_SetInterruptMask

(

uint32_t

intrMask

)

Sets the specified interrupt mask value.

This API is available only for PSoC 4500S and 4100S Max devices.

Parameters

intrMask

The mask of interrupts. Select one or more values from Interrupt Masks and "OR" them together. CY_SYSCLK_INTR_PLL_LOCK CY_SYSCLK_INTR_WD_ERR CY_SYSCLK_INTR_SW_IMO

Function Usage

    /* Scenario: Enable the CSV */
    Cy_SysClk_CsvInit(&csvConfig);
    Cy_SysClk_CsvEnable();
    Cy_SysClk_ClearInterrupt(CY_SYSCLK_INTR_SW_IMO);
    Cy_SysClk_SetInterruptMask(CY_SYSCLK_INTR_SW_IMO);
