Note1) When setting the RS/CS to be invalid, the RS signals from MCU can be always received, and the
CS signals are always ignored.
Note2) If the terminator is set to “Timeout=0”, the data reception will complete when the time for more
than approx. 3 characters has passed from the time that last data was received.
