ditions are met at the time the final shift pulse is

generated:

1. RI = 0, and

2. Either SM2 = 0, or the received 9th data bit = 1

If either of these conditions is not met, 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.
