Asynchronous Events

A MIL-1553 application can register condition(s) to be monitored by the firmware.

When a callback handler is defined, the condition(s) are reported to the application asynchronously from the firmware to the handler.

The way to define a handler is as follows:

• Initialize the application as usual.
• A callback handler must be registered using the mxfAsyncEventHandlerInit() function.
• The conditions to monitor must be defined using the mxfAsyncEventConditionsSet() function.

List of conditions

The event conditions that can be monitored for a RT channel are as follows:

Condition	Description
MXF_ASYNCEVENT_COND_RXACQ_BUFFER_THRESHOLD	Acquisition buffer threshold exceeded.
MXF_ASYNCEVENT_COND_RX_MSG	Specific message available in the queue.
MXF_ASYNCEVENT_COND_RX_ERROR	Receive errors on the RX port.
MXF_ASYNCEVENT_COND_TXPERIODIC_UPDATEMSG_BUFFER_THRESHOLD	Periodic update message buffer threshold reached.
MXF_ASYNCEVENT_COND_TX_ERROR	Transmit errors on the TX port.
