become divide by 4 of the oscillator clock. This results in faster synchronous serial
communication.
REN_1: Receive enable: When set to 1 serial reception is enabled, otherwise reception is disabled.
TB8_1: This is the 9th bit to be transmitted in modes 2 and 3. This bit is set and cleared by software
as desired.
RB8_1: In modes 2 and 3 this is the received 9th data bit. In mode 1, if SM2_1 = 0, RB8_1 is the stop
bit that was received. In mode 0 it has no function.
TI_1:
Transmit interrupt flag: This flag is set by hardware at the end of the 8th bit time in mode 0, or
at the beginning of the stop bit in all other modes during serial transmission. This bit must be
cleared by software.
RI_1: Receive interrupt flag: This flag is set by hardware at the end of the 8th bit time in mode 0, or
halfway through the stop bits time in the other modes during serial reception. However the
restrictions of SM2_1 apply to this bit. This bit can be cleared only by software.

Address: C1h
SBUF1.7-0: Serial data of the serial port 1 is read from or written to this location. It actually consists of
two separate 8-bit registers. One is the receive resister, and the other is the transmit
buffer. Any read access gets data from the receive data buffer, while write accesses are
to the transmit data buffer.
