Function Documentation

Cy_SCB_SPI_Interrupt()

void Cy_SCB_SPI_Interrupt	(	CySCB_Type *	base,
		cy_stc_scb_spi_context_t *	context
	)

This is the interrupt function for the SCB configured in the SPI mode.

This function must be called inside the user-defined interrupt service routine for Cy_SCB_SPI_Transfer to work.

Parameters

base	The pointer to the SPI SCB instance.
context	The pointer to the context structure cy_stc_scb_spi_context_t allocated by the user. The structure is used during the SPI operation for internal configuration and data retention. The user must not modify anything in this structure.

Cy_SCB_SPI_RegisterCallback()

__STATIC_INLINE void Cy_SCB_SPI_RegisterCallback	(	CySCB_Type const *	base,
		cy_cb_scb_spi_handle_events_t	callback,
		cy_stc_scb_spi_context_t *	context
	)

Registers a callback function, which notifies that SPI Callback Events occurred in the Cy_SCB_SPI_Interrupt.

Parameters

base	The pointer to the SPI SCB instance.
callback	The pointer to the callback function. See cy_cb_scb_spi_handle_events_t for the function prototype.
context	The pointer to the context structure cy_stc_scb_spi_context_t allocated by the user. The structure is used during the SPI operation for internal configuration and data retention. The user should not modify anything in this structure.

Note

• To remove the callback, pass NULL as the pointer to the callback function.
• To get the event notification, the corresponding interrupt mask needs to be set in the interrupt mask register so that interrupt request register can trigger an interrupt event in Cy_SCB_SPI_Interrupt.
