Function Documentation

int XSdiAud_CfgInitialize	(	XSdiAud *	InstancePtr,
		XSdiAud_Config *	CfgPtr,
		UINTPTR	EffectiveAddr
	)

This function initializes the XSdiAud.

This function must be called prior to using the core. Initialization of the XSdiAud includes setting up the instance data, and ensuring the hardware is in a quiescent state.

Parameters

InstancePtr	is a pointer to the XSdiAud instance.
CfgPtr	points to the configuration structure associated with the XSdiAud.
EffectiveAddr	is the base address of the device. If address translation is being used, then this parameter must reflect the virtual base address. Otherwise, the physical address should be used.

Returns

XST_SUCCESS : if successful.
XST_FAILURE : if version mismatched.

Note: None.

void XSdiAud_ConfigReset ( XSdiAud * InstancePtr )

This function is used to soft reset the XSdiAud registers.It resets all the configuration registers.

Parameters

InstancePtr is a pointer to the XSdiAud instance.

Returns: None.

void XSdiAud_CoreReset	(	XSdiAud *	InstancePtr,
		u8	RstCoreEnable
	)

This function is used to soft reset the XSdiAud core.

Parameters

InstancePtr	is a pointer to the XSdiAud instance.
RstCoreEnable	is to enable or disable. When set to 1(i.e.enable), it resets the embedded core. When set to 0, it clears the reset (i.e.disable).

Returns: None.
