1. RI = 0, and
2. Either SM2 = 0, or the received 9th data bit = 1
If eitherof these conditions is notmet, the received
frame is irretrievably lost, and RI is not set. If both
conditions are met, the received 9th data bit goes
into RB8, and the first 8 data bits go into SBUF.
One bit time later, whether the above conditions
were met or not, the unit goes back to looking for
a 1-to-0 transition at the RxD input.
