If both conditions are met, the stop bit goes into RB8,
the 8 data bits go into SBUF, and RI is activated. If one
of these conditions is not met, the received frame is
completely lost. At this time, whether the above
conditions are met or not, the unit goes back to
searching for a one to zero transition in RXD.
Mode 2
In Mode 2 a total of 11 bits are transmitted through
TXD or received through RXD. The transactions are
composed of: a Start bit (Low), 8 data bits (LSB first), a
programmable 9
th
data bit, and one Stop bit (High).
For transmission, the 9
th
data bit comes from the TB8
bit of SCON. For example, the parity bit P in the PSW
could be moved into TB8.
In the case of receive, the 9
th
data bit is automatically
written into RB8 of the SCON register.
In Mode 2, the baud rate is programmable to either
1/32 or 1/64 the oscillator frequency.
