NOTE:
Serial Communications Interface Modules (SCI1 and SCI2)
To verify the start bit and to detect noise, data recovery logic takes
samples at RT3, RT5, and RT7.
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.
The RT8, RT9, and RT10 data samples do not affect start bit verification.
If any or all of the RT8, RT9, and RT10 samples are logic 1s following a
successful start bit verification, the NF flag is set and the receiver
interprets the bit as a start bit (logic 0).
