The process for detecting stop bit is like clock and data recovery process. That is, if 2 or more samples of 3
center values have high level, correct stop bit is detected, else a frame error (FE1) flag is set. After deciding
whether the first stop bit is valid or not, the Receiver goes to idle state and monitors the RXD1 line to check a
valid high to low transition is detected (start bit detection).
