To verify the start bit and to detect noise, data recovery logic takes
samples at RT3, RT5, and RT7.
the start bit verification samples.
Start bit verification is not successful if any two of the three verification
samples are logic 1s. If start bit verification is not successful, the RT
clock is reset and a new search for a start bit begins.
To determine the value of a data bit and to detect noise, recovery logic
takes samples at RT8, RT9, and RT10.
