23.3.2.7 Data Entry Structures
A data entry must belong to a queue. The queues are set up as part of the command structure of a radio
operation command.
Operations on queues available as commands are described in
23.3.2.7.1 Data Entry Queue
Any command that uses a queue contains a pointer to a data entry queue structure, as given in
Table 23-9. The system CPU allocates and initializes this queue structure.
