Appendix B :
Each Module has a internal buffer register for the duty data register.
The buffer register is updated with the new data whenever the
When user write, the data register is written.
When user read, the contents of buffer register is read out.

The transmission buffer and the reception buffer are separated.
The transmission/reception buffers have the same address.
SBUF.6
(99h) : Serial Data Buffer Register
(98h) : Serial Port Control Register of UART0
SM1
: Enables the Automatic Address Recognition in Mode2 and 3.
: Enable/Disable reception.
: 9th data bit that will be transmitted in Mode2 and 3.
: 9th data bit that was received in Mode 2 and 3.
: Transmission interrupt flag. Must be cleared by S/W.
: Reception interrupt flag. Must be cleared by S/W.
In Mode1, the validity of a Stop Bit is checked if SM2=1
In Mode0, SM2 should be “0”.
In Mode1, RB8 is equal to stop bit if SM2 is “0”.
In Mode0, RB8 is not used.
: Serial Port mode selector.
