FUNCTION
the stop bit that was received. In mode 0 it has no function.
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.
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 apply to this bit. This bit can be
cleared only by software.

SBUF.[7:0]
consists of two separate internal 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 access is to the transmit data buffer.
