Table 141. Serial Port Buffer SFR (SBUF, Address 0x99)
Bit
[7:0]
Mnemonic
SBUF
Default
0
Description
Serial port data buffer.
Table 142. Enhanced Serial Baud Rate Control SFR (SBAUDT, Address 0x9E)
Bit
7
Mnemonic
OWE
Default
0
Description
Overwrite error. This bit is set when new data is received and RI = 1 (Bit 0 in the SCON SFR, Address
0x98). It indicates that SBUF was not read before the next character was transferred in, causing the
prior SBUF data to be lost. Write a 0 to this bit to clear it.
6
FE
0
Frame error. This bit is set when the received frame does not have a valid stop bit. This bit is read
only and updated every time a frame is received.
5
BE
0
Break error. This bit is set whenever the receive data line (Rx) is low for longer than a full transmission
frame, which is the time required for a start bit, eight data bits, a parity bit, and half a stop bit. This
bit is updated every time a frame is received.

Table 143. UART Timer Fractional Divider SFR (SBAUDF, Address 0x9D)
Bit
7
Mnemonic
UARTBAUDEN
Default
0
Description
UART baud rate enable. Set to enable UART timer to generate the baud rate. When set, the SMOD
bit (PCON[7]), the TCLK bit (T2CON[4]), and the RCLK bit (T2CON[5]) are ignored.
Cleared to let the baud rate be generated as per a standard 8052.
