USART control register 3
| EIE | Error interrupt enable 0 (B_0x0): Interrupt inhibited 1 (B_0x1): interrupt generated when FE=1 or ORE=1 or NE=1 or UDR = 1 (in SPI slave mode) in the USART_ISR register. |
| IREN | IrDA mode enable 0 (B_0x0): IrDA disabled 1 (B_0x1): IrDA enabled |
| IRLP | IrDA low-power 0 (B_0x0): Normal mode 1 (B_0x1): Low-power mode |
| HDSEL | Half-duplex selection 0 (B_0x0): Half-duplex mode is not selected 1 (B_0x1): Half-duplex mode is selected |
| NACK | Smartcard NACK enable 0 (B_0x0): NACK transmission in case of parity error is disabled 1 (B_0x1): NACK transmission during parity error is enabled |
| SCEN | Smartcard mode enable 0 (B_0x0): Smartcard mode disabled 1 (B_0x1): Smartcard mode enabled |
| 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 USART_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. |
| SCARCNT | Smartcard auto-retry count 0 (B_0x0): retransmission disabled - No automatic retransmission in transmission mode. |

| 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 USART_ISR register |
| TCBGTIE | Transmission Complete before guard time, interrupt enable 0 (B_0x0): Interrupt inhibited 1 (B_0x1): USART interrupt generated whenever TCBGT=1 in the USART_ISR register |
