If 1, 2 or more parameter command is being sent and a break occurs while sending any parameter before the last one and if the host then
sends a new command rather than re-transmitting the parameter that was interrupted, then the parameters that were successfully sent are
stored and the parameter where the break occurred is rejected. The interface is ready to receive next byte as shown below.
If a 2 or more parameter command is being sent and a break occurs by the other command before the last one is sent, then the parameters
that were successfully sent are stored and the other parameter of that command remains previous value.
