Notifying the Application of FIFO Events: cbackSuni4x622FIFO
This callback function is provided by the USER and is used by the DPR to report significant
FIFO section events back to the application. This function should be non-blocking. Typically, the
callback routine sends a message to another task with the event identifier and other context
information. The task that receives this message can then process this information according to
the system requirements. Note: the callback function’s addresses are passed to the driver doing
the
suni4x622Init call. If the address of the callback function was passed as a NULL at
initialization no callback will be made.
