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
MPBT—Multiprocessor Bit Transmit
This bit is applicable only when MULTIPROCESSOR (9-bit) mode is enabled. The 9th bit
is used by the receiving device to determine if the data byte contains address or data infor-
mation.
