: 9th data bit that will be transmitted in Mode 2 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.
SM1
Clear after receiving the address.
In Mode 1, the Validity of the Stop Bit is checked if SM2=1.
In Mode 0, SM2 should be 0.
In Mode 1, RB8 is equal to Stop Bit if SM2=0.
In Mode 0, RB8 is not used.
[0,0] : Mode 0. 8-bit Shift Register (OSC/4)
[0,1] : Mode 1. 8-bit UART (Variable)
[1,0] : Mode 2. 9-bit UART (OSC/32 or OSC/16)
[1,1] : Mode 3. 9-bit UART (Variable)
