Functions
static bool_t	AR_Interrupt_run ()
	AR_Interrupt_run queries the user for the card, module and channel to configure as the ARINC transmitter as well as the data rate (high (100KHz) or low (12.5KHz)). Methods in the naibrd library are invoked to configure the ARINC channel. The user-specified ARINC channel is configured with the Tx FIFO Threshold set to 32 messages, which means that the Tx FIFO Full status bit will be set and, if enabled, an interrupt will be generated when the Tx FIFO reaches 32 messages at any point in time. In order to be able to accumulate messages in the Tx FIFO, the Tx FIFO send mode is set to Triggered Mode, which requires the user to send a Trigger signal in order for the contents of the Tx FIFO to get sent out. This code demonstrates how to program the ARINC module to generate an interrupt when the Tx FIFO Full event occurs.
