Description

[7]



TEN

Transmit Enable

This bit enables or disables the transmitter. The enable is also controlled by the CTS signal

and the CTSE bit. If the CTS signal is Low and the CTSE bit is 1, the transmitter is enabled.



0 = Transmitter disabled.



1 = Transmitter enabled.

[6]



REN

Receive Enable

This bit enables or disables the receiver.



0 = Receiver disabled.



1 = Receiver enabled.

[5]



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.

[4]



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 addi-

tional parity bit.

[3]



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.

[2]



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.

[1]



STOP

Stop Bit Select

0 = The transmitter sends one stop bit.



1 = The transmitter sends two stop bits.

[0]



LBEN

Loop Back Enable

0 = Normal operation.



1 = All transmitted data is looped back to the receiver.
