Rev. PrD | Page 117 of 140
In Modes 2 or 3, if SM2 is set, RI is not activated if the received ninth data bit in RB8 is
0. If SM2 is cleared, RI is set as soon as the byte of data is received.

0
Serial Port Receive Enable Bit.
Set by user software to enable serial port reception.
Cleared by user software to disable serial port reception.

0x9B
TB8
0
Serial Port Transmit (Bit 9).
The data loaded into TB8 is the ninth data bit transmitted in Modes 2 and 3.
2
0x9A
RB8
0
Serial Port Receiver Bit 9.
The ninth data bit received in Modes 2 and 3 is latched into RB8. For Mode 1, the stop
bit is latched into RB8.

0x99
TI
0
Serial Port Transmit Interrupt Flag.
Set by hardware at the end of the eighth bit in Mode 0, or at the beginning of the stop
bit in Modes 1, 2, and 3.
TI must be cleared by user software.
Serial Port Receive Interrupt Flag.
0
0x98
RI
0
Set by hardware at the end of the eighth bit in Mode 0, or halfway through the stop bit
in Modes 1, 2, and 3.
RI must be cleared by user software.

Description
Serial port data buffer
Bit
Default
Description
Overwrite Error. This bit is set when new data is received and RI=1. It indicates that
SBUF was not read before the next character was transferred in, causing the prior
SBUF data to be lost.
Frame Error. This bit is set when the received frame did not have a valid stop bit. This
bit is read only and updated every time a frame is received.
Break Error. This bit is set whenever the receive data line (Rx) is low for longer than a
full transmission frame, the time required for a start bit, 8 data bits, a parity bit and half
a stop bit. This bit is updated every time a frame is received.
