DETAILED MODE CODES FUNCTIONAL
DESCRIPTION
The applicable Mode Codes for the SSRT are described below:
DYNAMIC BUS CONTROL (
= 1; 00000)
MESSAGE SEQUENCE = DBC + STATUS
The SSRT responds with Status showing non-acceptance of the mode code command.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message error bit (Status Word), High Word Count (BIT Word).
3.
bit Set to Zero. No Status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
bit and Broadcast Address. No Status response. Set Message Error and Broadcast Received bits (Status Word),
Command Word Contents Error (BIT Word).
5. Broadcast Address. No Status response. Set Message Error and Broadcast Received bits (Status Word),
Command Word Contents Error (BIT Word).

SYNCHRONIZE WITHOUT DATA WORD (
= 1; 00001)
MESSAGE SEQUENCE = SYNC + STATUS
The SSRT responds with Status.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word), High Word Count (BIT Word).
3.
bit Set to Zero. No Status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
bit and Broadcast Address. No Status response. Set Message Error and Broadcast Received bits (Status Word),
Command Word Contents Error (BIT Word).

TRANSMIT STATUS WORD (
= 1; 00010)
MESSAGE SEQUENCE = TRANSMIT STATUS + STATUS
The Status register is not updated before it is transmitted and contains the resulting status from the previous command (assuming that it was not
a Transmit status or Transmit last command mode command).
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word)
3.
bit Set to Zero .No Status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
bit and Broadcast Address. No Status response. Set Message Error and Broadcast Received bits (Status Word),
Command Word Contents Error (BIT Word).
5. Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status Word),
Command Contents Error (BIT Word).

INITIATE SELF-TEST (
= 1; 00011)
MESSAGE SEQUENCE = SELF TEST + STATUS
If the command was non-broadcast, the SSRT responds with Status. If the command was either non-broadcast or broadcast, the SSRT will go
offline and perform its internal off-line protocol self-test. The self-test exercises the SSRT's encoder and decoders, registers, transmitter watchdog
timer, and protocol logic. This test is completed in approximately 32,000 clock cycles. That is, about 1.6 ms with a 20 MHz clock, 2.0 ms at 16
MHz, 2.7 ms at 12 MHz, and 3.2 ms at 10 MHz.
While the SSRT is performing its off-line self-test, it will ignore (and therefore not respond to) all messages received from the 1553 bus. The bus
controller may determine the result of the self-test be means of a Transmit BIT word mode command. If the self-test passes, bit 8 of the SSRT's
BIT word (BIT Test Fail) will be logic "0"; if the self-test fails, this bit will be logic "1". In addition, if self-test fails, the terminal flag status word bit will
be set to logic “1” in response to the next non-broadcast message.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word), High Word Count (BIT Word).
3.
bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
bit and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status word),
Command Word Contents Error (BIT Word).
5. Loopback Test Failure. Set Terminal Flag bit in internal Status register (Status Word for next non-broadcast command),
Current Channel (A or B) Loop Test Failure and CH A/B Loop Test Failure (BIT Word), assert
output.
