Description

LPUART Modem IrDA Register

Fields

TXCTSE

Transmitter clear-to-send enable

0 (0): CTS has no effect on the transmitter.

1 (1): Enables clear-to-send operation. The transmitter checks the state of CTS each time it is ready to send a character. If CTS is asserted, the character is sent. If CTS is deasserted, the signal TXD remains in the mark state and transmission is delayed until CTS is asserted. Changes in CTS as a character is being sent do not affect its transmission.

TXRTSE

Transmitter request-to-send enable

0 (0): The transmitter has no effect on RTS.

1 (1): When a character is placed into an empty transmitter data buffer , RTS asserts one bit time before the start bit is transmitted. RTS deasserts one bit time after all characters in the transmitter data buffer and shift register are completely sent, including the last stop bit.

TXRTSPOL

Transmitter request-to-send polarity

0 (0): Transmitter RTS is active low.

1 (1): Transmitter RTS is active high.

RXRTSE

Receiver request-to-send enable

0 (0): The receiver has no effect on RTS.

TXCTSC

Transmit CTS Configuration

0 (0): CTS input is sampled at the start of each character.

1 (1): CTS input is sampled when the transmitter is idle.

TXCTSSRC

Transmit CTS Source

0 (0): CTS input is the CTS_B pin.

1 (1): CTS input is the inverted Receiver Match result.

RTSWATER

Receive RTS Configuration

TNP

Transmitter narrow pulse

0 (00): 1/OSR.

1 (01): 2/OSR.

2 (10): 3/OSR.

3 (11): 4/OSR.

IREN

Infrared enable

0 (0): IR disabled.

1 (1): IR enabled.
