Toggle flag (T)
The toggle flag is used to uniquely identify a new valid command. The control
interface only accepts and executes a new command if this flag has a different
status to the previous command, i.e. when it is toggled.
When the control interface on the DP master is acknowledged, the toggle flag is
not changed and indicates to the user that the control interface has received and
processed the command.
Note!
The command is only executed if the execution counter  0.
