PSEL—Parity Select
0 = Even parity is transmitted and expected on all received data.
1 = Odd parity is transmitted and expected on all received data.
SBRK—Send Break
This bit pauses or breaks data transmission by forcing the Transmit data output to 0.
Sending a break interrupts any transmission in progress, so ensure that the transmitter has
finished sending data before setting this bit. The UART does not automatically generate a
STOP Bit when SBRK is deasserted. Software must time the duration of the Break and the
duration of any STOP Bit time desired following the Break.
0 = No break is sent.
1 = The output of the transmitter is zero.
STOP—STOP Bit Select
0 = The transmitter sends one stop bit.
1 = The transmitter sends two stop bits.
LBEN—Loop Back Enable
0 = Normal operation.
1 = All transmitted data is looped back to the receiver.
MPMD[1:0]—Multiprocessor Mode
If Multiprocessor (9-bit) mode is enabled,
00 = The UART generates an interrupt request on all received bytes (data and address).
01 = The UART generates an interrupt request only on received address bytes.
10 = The UART generates an interrupt request when a received address byte matches
11 = The UART generates an interrupt request on all received data bytes for which
MPEN—Multiprocessor (9-bit) Enable
This bit is used to enable Multiprocessor (9-bit) mode.
0 = Disable Multiprocessor (9-bit) mode.
1 = Enable Multiprocessor (9-bit) mode.

bytes until an address mismatch occurs.
the most recent address byte matched the value in the Address Compare Register.
