Product Specification

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.

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
