Description:
It is a test application in which a communication between several MCUs is 
performed.Baud rate 4800, no parity, 1 stop bit and a data length of 8 bit. 
The master MCU works all the time in mode 3, the slave MCU changes between 
mode 2 and mode 3. Mode 3 for the slave is necessary to communicate with the 
master. All slave MCUs which are still in mode 2 are ignoring the data on the 
bus, because to communicate in mode 2 it is necessary that D8 in the URD0-register
is set to '1' all the time.
