SYNCHRONIZE WITHOUT DATA WORD (01)
The device will respond with status. The NSYNC signal will go
active low for 500 nS. Throughout this period the highway T0-

received.
If the command was a broadcast the status transmission will be
suppressed and the broadcast bit in the status register set.
TRANSMIT STATUS (02)
The status register is not cleared or loaded before it is transmitted,
i.e. it contains the resulting status from the previous command.

If the command was a broadcast the status transmission will be
suppressed and the broadcast bit in the status register set.
TRANSMITTER SHUTDOWN (04)
The device will respond with status and shutdown the transmitter
on the alternate bus, thus inhibiting any further transmission on that
bus.
Once a transmitter has been shutdown it can only be reactivated by
the mode commands 'Override Transmitter Shutdown' 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.
