PEN—Parity Enable
This bit enables or disables parity. Even or odd is determined by the PSEL bit.
0 = Parity is disabled.
1 = The transmitter sends data with an additional parity bit and the receiver receives an
additional parity bit.
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. Sending a break interrupts any transmission in
progress, so ensure that the transmitter has finished sending data before setting this bit.
0 = No break is sent.
1 = Forces a break condition by setting the output of the transmitter to 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 the
value stored in the Address Compare Register and on all successive data bytes until an
address mismatch occurs.
11 = The UART generates an interrupt request on all received data bytes for which the
most recent address byte matched the value in the Address Compare Register.
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.
