Threshold flag is set if more than sixteen messages are in the FIFO (default)  
Threshold flag is set if 32 messages are in the FIFO (Same as FIFO FULLFLAG)  
ARINC 429 Loop-back Self-Test  
The HI-3200 includes an ARINC 429 loop-back feature,  
which allows users to exercise theARINC 429 transmit and  
receive channels for self-test purposes. The ARINC 429  
Loop-Back register, ALOOP defines which receiver  
channels are in loop-back mode. When a “1” is  
programmed in the ALOOP bit position for a receiver, then  
itsARINC 429 bus connection to the external pins is broken  
and instead the input is connected to one of the fourARINC  
429 transmit channels. Transmit channel 0 is connected to  
receive channel 0 and 1, transmit channel 1 is connected to  
receive channels 2 and 3, and so on.  
When in loop-back mode, incoming ARINC 429 messages  
are ignored by the HI-3200. When running in loop-back  
mode the ARINC 429 transmit pins may be disabled by  
pulling the TXMSK input high. This prevents test messages  
from being output to the external ARINC 429 transmit  
buses.
