Function Documentation

int XScuWdt_CfgInitialize (  XScuWdt *  InstancePtr,
XScuWdt_Config *  ConfigPtr,
u32  EffectiveAddress
) 
 

Initialize a specific watchdog timer instance/driver. This function must be called before other functions of the driver are called.

Parameters:
InstancePtr is a pointer to the XScuWdt instance.
ConfigPtr is the config structure.
EffectiveAddress is the base address for the device. It could be a virtual address if address translation is supported in the system, otherwise it is the physical address.
Returns:
  • XST_SUCCESS if initialization was successful.
