To determine the value of a data bit and to detect noise, recovery logic takes samples at RT8, RT9, and

To verify a stop bit and to detect noise, recovery logic takes samples at RT8, RT9, and RT10.

The RT8, RT9, and RT10 samples do not affect start bit veriﬁcation. If any

or all of the RT8, RT9, and RT10 start bit samples are logic 1s following a

successful start bit veriﬁcation, the noise ﬂag (NF) is set and the receiver

assumes that the bit is a start bit (logic 0).
