Description

LPUART control register 3

Fields

EIE

Error interrupt enable

0 (B_0x0): Interrupt is inhibited

1 (B_0x1): An interrupt is generated when FE=1 or ORE=1 or NE=1 in the LPUART_ISR register.

HDSEL

Half-duplex selection

0 (B_0x0): Half-duplex mode is not selected

1 (B_0x1): Half-duplex mode is selected

DMAR

DMA enable receiver

0 (B_0x0): DMA mode is disabled for reception

1 (B_0x1): DMA mode is enabled for reception

DMAT

DMA enable transmitter

0 (B_0x0): DMA mode is disabled for transmission

1 (B_0x1): DMA mode is enabled for transmission

RTSE

RTS enable

0 (B_0x0): RTS hardware flow control disabled

1 (B_0x1): RTS output enabled, data is only requested when there is space in the receive buffer.

CTSE

CTS enable

0 (B_0x0): CTS hardware flow control disabled

1 (B_0x1): CTS mode enabled, data is only transmitted when the CTS input is deasserted (tied to 0).

CTSIE

CTS interrupt enable

0 (B_0x0): Interrupt is inhibited

1 (B_0x1): An interrupt is generated whenever CTSIF=1 in the LPUART_ISR register

OVRDIS

Overrun Disable

0 (B_0x0): Overrun Error Flag, ORE is set when received data is not read before receiving new data.

1 (B_0x1): Overrun functionality is disabled.

DDRE

DMA Disable on reception Error

0 (B_0x0): DMA is not disabled in case of reception error.

1 (B_0x1): DMA is disabled following a reception error.

DEM

Driver enable mode

0 (B_0x0): DE function is disabled.

1 (B_0x1): DE function is enabled.

DEP

Driver enable polarity selection

0 (B_0x0): DE signal is active high.

1 (B_0x1): DE signal is active low.

WUS0

Wake-up from low-power mode interrupt flag selection

0 (B_0x0): WUF active on address match (as defined by ADD[7:0] and ADDM7)

WUS1

Wake-up from low-power mode interrupt flag selection

0 (B_0x0): WUF active on address match (as defined by ADD[7:0] and ADDM7)

WUFIE

Wake-up from low-power mode interrupt enable

0 (B_0x0): Interrupt inhibited

1 (B_0x1): USART interrupt generated whenever WUF=1 in the LPUART_ISR register
