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.

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.

CD1, CD0: Clock Divide Control. These bit selects the number of clocks required to generate one
machine cycle. There are three modes including divide by 4, 64 or 1024. Switching
between modes must first go back divide by 4 mode. For instance, to go from 64 to 1024
locks/machine cycle the device must first go from 64 to 4 clocks/machine cycle, and then
from 4 to 1024 clocks/machine cycle.
