Function Documentation

◆ Cy_DMAC_Descriptor_Init()

cy_en_dmac_status_t Cy_DMAC_Descriptor_Init	(	DMAC_Type *	base,
		uint32_t	channel,
		cy_en_dmac_descriptor_t	descriptor,
		const cy_stc_dmac_descriptor_config_t *	config
	)

Initializes the descriptor structure from a pre-initialized configuration structure.

This function initializes only one ping/pong descriptor and not the channel.

Parameters

base	The pointer to the hardware DMAC block.
channel	A channel number.
descriptor	The ping/pong descriptor.
config	This is a configuration structure that has all initialization information for the descriptor.

Returns: The status /ref cy_en_dmac_status_t.

Function Usage: /* Scenario: Initialize the single ping descriptor */
#define DATA_CNT (8U)
#define CHANN_NUM (0U)
uint32_t src[DATA_CNT];
uint32_t dst[DATA_CNT];
/* Descriptor ping configuration structure */

};
/* Initialize the ping descriptor for channel 0 */
if (CY_DMAC_SUCCESS != Cy_DMAC_Descriptor_Init(DMAC, CHANN_NUM, CY_DMAC_DESCRIPTOR_PING, &descriptorPingCfg))
{

◆ Cy_DMAC_Descriptor_DeInit()

void Cy_DMAC_Descriptor_DeInit	(	DMAC_Type *	base,
		uint32_t	channel,
		cy_en_dmac_descriptor_t	descriptor
	)

Clears the content of the specified descriptor.

Parameters

base	The pointer to the hardware DMAC block.
channel	The channel number.
descriptor	The descriptor structure instance.

Function Usage: /* Scenario: Invalidate the pong descriptor for channel 0 */
#define CHANN_NUM (0U)
if (CHANN_NUM != Cy_DMAC_GetActiveChannel(DMAC))
{
/* Make sure it is not in use */
if (CY_DMAC_DESCRIPTOR_PONG != Cy_DMAC_Channel_GetCurrentDescriptor(DMAC, CHANN_NUM))
{

}

◆ Cy_DMAC_Descriptor_SetState()

__STATIC_INLINE void Cy_DMAC_Descriptor_SetState	(	DMAC_Type *	base,
		uint32_t	channel,
		cy_en_dmac_descriptor_t	descriptor,
		bool	valid
	)

Sets the state of the specified descriptor.

Parameters

base	The pointer to the hardware DMAC block.
channel	The channel number.
descriptor	The ping/pong descriptor.
valid	true - validate, false - invalidate.

Note: If descriptor is initialized dynamically there is a need to set state to invalid before initialization and to valid after. Do this to prevent the descriptor execution with wrong parameters.

Function Usage: /* Scenario: Enable the descriptor and channel after an invalidated descriptor trigger */
#define CHANN_NUM (0U)
cy_en_dmac_response_t descrResp;
descrResp = Cy_DMAC_Descriptor_GetResponse(DMAC, CHANN_NUM, CY_DMAC_DESCRIPTOR_PING);
