MODE CODES
The BU-61703/5 fully implements all 13 of the dual redundant
MIL-STD-1553B mode codes. Four mode codes, Transmit vector
word, Synchronize (with data), Selected transmitter shutdown,
and Override transmitter shutdown, involve data transfers with
the subsystem. For the Transmit last command mode command,
the data word transmitted is from the SSRT's last command
internal register. For the Transmit BIT word mode command, the
SSRT's internally formulated BIT Word is transmitted. Table 6
provides a summary of the 1553B mode codes supported by the
BU-61703/5.
SUMMARY OF RESPONSES TO MODE CODE
MESSAGES
The SSRT's responses to mode codes, including responses to
various error conditions, are summarized in Table 6.
