OVERRIDE TRANSMITTER SHUTDOWN (05)
* ^{TX EN}
CMD
STATUS
The device will respond with status and reactivate a shutdown
transmitter on the alternate bus.
If the command was a broadcast the status transmission will be
suppressed and the broadcast bit in the status register set.
Error Conditions
1. Invalid command.
2. Command followed by
another word.
3. T/R bit of command set
to zero.
4. T/R bit of command set
to zero and broadcast
address
Action taken by device
No response.
Command ignored.
No status response.
Set message error.
Sequence terminated.

INHIBIT TERMINAL FLAG (06)
* ^{INH TF}
CMD
STATUS
The device will respond with status and then inhibit any further
setting of the Terminal Flag bit of the status.
Once the Terminal Flag bit has been inhibited it can only be
reactivated by the mode commands 'Override Inhibit Terminal
Flag' or 'Reset Remote Terminal'.
If the command was a broadcast the status transmission will be
suppressed and the broadcast bit in the status register set.
Error Conditions
1. Invalid command.
2. Command followed by
another word.
3. T/R bit of command set
to zero.
4. T/R bit of command set
to zero and broadcast
address

OVERRIDE INHIBIT TERMINAL FLAG (07)
* ^{EN TF}
CMD
STATUS
The device will respond with status and then reactivate the
Terminal Flag bit of the status register.
If the command was a broadcast the status transmission will be
suppressed and the broadcast bit in the status register set.
Error Conditions
1. Invalid command.
2. Command followed by
another word.
3. T/R bit of command set
to zero.
4. T/R bit of command set

RESET REMOTE TERMINAL (08)
* ^RESET
CMD
STATUS
The device will respond with status after which the bidirectional
signal NRES to the subsystem will go active low for 500 nS.
Transmitter Shutdown mode commands and Inhibit Terminal Flag
mode command will be reactivated.
If the command was a broadcast the status transmission will be
suppressed and the broadcast bit in the status register set.
Error Conditions
1. Invalid command.
2. Command followed by
another word.
3. T/R bit of command set
to zero.
4. T/R bit of command set
to zero and broadcast
address
