enabled.
0 = Transmitter disabled.
1 = Transmitter enabled.
REN—Receive Enable
This bit enables or disables the receiver.
0 = Receiver disabled.
1 = Receiver enabled.
CTSE—CTS Enable
0 = The CTS signal has no effect on the transmitter.
1 = The UART recognizes the CTS signal as an enable control from the transmitter.
PEN—Parity Enable
This bit enables or disables parity. Even or odd is determined by the PSEL bit. It is over-
ridden by the MPEN 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 = 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.
