5.11 Callback Functions
Proprietary and Confidential to PMC-Sierra, Inc., and for its Customers’ Internal Use
Document ID: PMC-2021248, Issue 1
The Narrowband Chipset driver has the capability to callback functions within the user code
when certain events occur. The names given to the callback functions are given as examples. The
addresses of the callback functions are passed during the
To avoid using the callbacks, the user should set the address of the callback functions to NULL
within the MIV.
Notifying the Application of ILC data received events: cbackIlcRxData
This callback function is provided by the user and is used by the CSD to report in-band link data
received 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 address is passed to the driver during the

initialization, then no callback will be made. Since DPV buffer is not employed, there is no need
