RTY: Maximum value of retry times. Transmission error occurs if the actual retry has exceeds this setup
value.
M/S: Switching of master and slave. When contention of ENQ has occurred, the module decides which

Priority is given to the transmitter which is set up as a master. (0: Slave mode, 1 : Master mode)
