C868
On-Chip Peripheral Components
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 bit goes 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.
Note that the value of the received stop bit is irrelevant to SBUF, RB8 or RI.
