Function Documentation

◆ Cy_LVD_Enable()

__STATIC_INLINE void Cy_LVD_Enable ( void )

Enables the output of the LVD block when the VDDD voltage is at or below the threshold.

See the Configuration Considerations section for details.

◆ Cy_LVD_Disable()

__STATIC_INLINE void Cy_LVD_Disable ( void )

Disables the LVD block.

A low voltage detection interrupt is disabled.

◆ Cy_LVD_SetThreshold()

__STATIC_INLINE void Cy_LVD_SetThreshold ( cy_en_lvd_tripsel_t threshold )

Sets a threshold for monitoring the VDDD voltage.

To prevent propagating a false interrupt, before changing the threshold ensure that the LVD block itself and LVD interrupt are disabled by the Cy_LVD_Disable and Cy_LVD_ClearInterruptMask functions correspondingly.

Parameters

threshold Threshold selection for Low Voltage Detect circuit, cy_en_lvd_tripsel_t.

◆ Cy_LVD_GetStatus()

__STATIC_INLINE cy_en_lvd_status_t Cy_LVD_GetStatus ( void )

Returns the status of LVD.

SRSS LVD Status Register (PWR_LVD_STATUS).

Returns: LVD status, cy_en_lvd_status_t.

◆ Cy_LVD_GetInterruptStatus()

__STATIC_INLINE uint32_t Cy_LVD_GetInterruptStatus ( void )

Returns the status of LVD interrupt.

SRSS Interrupt Register (SRSS_INTR).

Returns: SRSS Interrupt status, CY_LVD_INTR.

◆ Cy_LVD_ClearInterrupt()

__STATIC_INLINE void Cy_LVD_ClearInterrupt ( void )

Clears LVD interrupt.

SRSS Interrupt Register (SRSS_INTR).

◆ Cy_LVD_SetInterrupt()

__STATIC_INLINE void Cy_LVD_SetInterrupt ( void )

Triggers the device to generate interrupt for LVD.

SRSS Interrupt Set Register (SRSS_INTR_SET).

◆ Cy_LVD_GetInterruptMask()

__STATIC_INLINE uint32_t Cy_LVD_GetInterruptMask ( void )

Returns the mask value of LVD interrupts.

SRSS Interrupt Mask Register (SRSS_INTR_MASK).

Returns: SRSS Interrupt Mask value, CY_LVD_INTR.

◆ Cy_LVD_SetInterruptMask()

__STATIC_INLINE void Cy_LVD_SetInterruptMask ( void )

Enables LVD interrupts.

Sets the LVD interrupt mask in the SRSS_INTR_MASK register.

◆ Cy_LVD_ClearInterruptMask()

__STATIC_INLINE void Cy_LVD_ClearInterruptMask ( void )

Disables LVD interrupts.

Clears the LVD interrupt mask in the SRSS_INTR_MASK register.

◆ Cy_LVD_GetInterruptStatusMasked()

__STATIC_INLINE uint32_t Cy_LVD_GetInterruptStatusMasked ( void )

Returns the masked interrupt status which is a bitwise AND between the interrupt status and interrupt mask registers.

SRSS Interrupt Masked Register (SRSS_INTR_MASKED).

Returns: SRSS Interrupt Masked value, CY_LVD_INTR.

◆ Cy_LVD_SetInterruptConfig()

__STATIC_INLINE void Cy_LVD_SetInterruptConfig ( cy_en_lvd_intr_config_t lvdInterruptConfig )

Sets a configuration for LVD interrupt.

SRSS Interrupt Configuration Register (SRSS_INTR_CFG).
