setting the address pointer to Null in the call to upper layer functions, or when inserted in the
ASL queue.

Stack Specific Packet
The stack specific IPC data packets are used for non-ISA100 functions as mentioned in Stack
Specific Packet Types. Addition of a stack specific function requires special handling functions,
which in turn increases the flash and sometimes RAMS utilization. In addition, these functions
are not prioritized in the ASL queue and can disrupt normal DMAP APDU message processing.
For these reasons, this class of data has been only implemented and used if an operation cannot
be achieved using the local support for ASL queued APDU services.
Stack Specific Packet Types
The Sensor uses ASL queued APDU class requests and APDU indications for both local and
network APDU packets.
For Stack Specific Class, the following packet types are supported:
