This function macro enables individual interrupts of the VTC core by updating the IRQ_ENABLE register.

Parameters

InstancePtr	is a pointer to the VTC core instance to be worked on.
IntrType	is the bit-mask of the interrupts to be enabled. Bit positions of 1 will be enabled. Bit positions of 0 will keep the previous setting. This mask is formed by OR'ing XVTC_IXR_*_MASK bits defined in xvtc_hw.h.

Returns: None.

Note: The existing enabled interrupt(s) will remain enabled. C-style signature: void XVtc_IntrEnable(XVtc *InstancePtr, u32 IntrType)

#define XVtc_IntrGetPending ( InstancePtr )

Value:

	 XVtc_ReadReg((InstancePtr)->Config.BaseAddress, XVTC_ISR_OFFSET) & \
	 XVTC_IXR_ALLINTR_MASK)

This function macro returns the pending interrupts of the VTC core for the interrupts that have been enabled.

Parameters

InstancePtr is a pointer to the VTC core instance to be worked on.

Returns: The pending interrupts of the VTC core. Use XVTC_IXR_*_MASK constants defined in xvtc_hw.h to interpret this value. The returned value is a logical AND of the contents of the STATUS Register and the IRQ_ENABLE Register.

This function initializes the VTC core.

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

Parameters

InstancePtr	is a pointer to the VTC core instance to be worked on.
CfgPtr	points to the configuration structure associated with the VTC core.
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 XVtc_CfgInitialize was successful.
