Oscillator Frequency (MHz)
* Assumes SMOD=1 and T1M=1.
** Numbers in parenthesis show the actual baud rate.
This is actually two registers; a transmit and a receive buffer register. When data is moved to
SBUF, it goes to the transmit buffer and is held for serial transmission. Moving a byte to
SBUF is what initiates the transmission. When data is moved from SBUF, it comes from the
receive buffer.
