Description

TXFE

0x1

Transmit FIFO empty. If the FIFO is disabled (bit FEN = 0b),

this bit is set when the transmit holding register is empty. If the

FIFO is enabled (FEN = 1b), the TXFE bit is set when the

transmit FIFO is empty.

DCTS

0x1

Delta Clear To Send. This bit is set CTS changes since the

last read of the FR register.

RTXDIS

0x0

Remote Transmitter Disabled (software flow control). This bit

indicates an Xoff character was sent to the remote transmitter

to stop it after the received FIFO has passed over its trigger

limit. This bit is cleared when a Xon character is sent to the

remote transmitter.

PEN_RX

0x0

RX parity enable:

0: Parity disabled.

1: Parity enabled.

EPS_RX

0x0

RX even parity selection, when the parity is enabled.

0: Odd parity generation and checking is performed during

reception, which check for an odd number of 1s in data and

parity bits.

1: Even parity generation and checking is performed during

reception, which check for an even number of 1s in data and

parity bits.

STP2_RX

0x0

RX two stop bits select. This bit enables the check for two stop

bits being received:

0: 1 stop bit received.

1: 2 stop bits received.

FEN_RX

0x0

RX enable FIFOs. This bit enables/disables the receive RX

FIFO buffer:

0: RX FIFO is disabled (character mode).

1: RX FIFO is enabled.

6:5

WLEN_RX

0x0

RX Word length. This bit field indicates the number of data bits

received in a frame as follows:

00b: 5 bits.

01b: 6 bits.

10b: 7 bits.

11b: 8 bits.
