MC68HC908AS60 — Rev. 1.0
NOTE:
To determine the value of a data bit and to detect noise, recovery logic
takes samples at RT8, RT9, and RT10.
results of the data bit samples.
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.
To verify a stop bit and to detect noise, recovery logic takes samples at
RT8, RT9, and RT10.
