BUILT-IN-TEST
The BUS-65142 contains a 14-bit Built-In-Test (BIT) word regis-
ter which stores information about the condition of the RTU.
When a mode code is received to transmit the BIT word, the con-
tents of the BIT register is transmitted over the 1553 bus.
FIGURE 2 shows the fault assigned to each bit in the BIT word.
Conditions monitored are; transmitter timeouts, loop test failures,
transmitter shutdown, subsystem handshake failure, and the
results of individual message validations.

1. BITS 3-7 ARE CLEARED IN THE BEGINNING OF EACH NEW MESSAGE AND UPDATED AT THE END OF THE MESSAGE.
THEY ONLY REFLECT THE PRESENT COMMAND WORD.
2. BITS 0-2 AND 10-13 ARE LATCHED AND ONLY CLEARED BY A MODE RESET COMMAND OR A MASTER RESET (RESET).
NOTES
3. BITS 8 AND 9 ARE SET ONLY BY THE MODE COMMAND FOR "TRANSMITTER SHUTDOWN" AND ARE CLEARED BY THE MODE COMMAND
FOR "OVERRIDE TRANSMITTER SHUTDOWN" OR "RESET REMOTE TERMINAL". BITS 8 AND 9 ARE ALSO CLEARED BY RESET.
