UARTEN: UARTx Enable bit
1 = UARTx is enabled; all UARTx pins are controlled by UARTx as defined by UEN<1:0>
0 = UARTx is disabled; all UARTx pins are controlled by port latches; UARTx power consumption is
minimal
Unimplemented: Read as ‘0’
USIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
IREN: IrDA^® Encoder and Decoder Enable bit⁽¹⁾
1 = IrDA encoder and decoder are enabled
0 = IrDA encoder and decoder are disabled
RTSMD: Mode Selection for UxRTS Pin bit
1 = UxRTS pin is in Simplex mode
0 = UxRTS pin is in Flow Control mode
Unimplemented: Read as ‘0’
UEN<1:0>: UARTx Enable bits⁽²⁾
11 = UxTX, UxRX and UxBCLK pins are enabled and used; UxCTS pin is controlled by port latches
10 = UxTX, UxRX, UxCTS and UxRTS pins are enabled and used
01 = UxTX, UxRX and UxRTS pins are enabled and used; UxCTS pin is controlled by port latches
00 = UxTX and UxRX pins are enabled and used; UxCTS and UxRTS/UxBCLK pins are controlled by port
latches
WAKE: Wake-up on Start Bit Detect During Sleep Mode Enable bit
1 = UARTx will continue to sample the UxRX pin; interrupt generated on falling edge, bit is cleared in
hardware on the following rising edge
0 = No wake-up is enabled
LPBACK: UARTx Loopback Mode Select bit
1 = Enable Loopback mode
0 = Loopback mode is disabled
ABAUD: Auto-Baud Enable bit
1 = Enable baud rate measurement on the next character – requires reception of a Sync field (55h);
cleared in hardware upon completion
0 = Baud rate measurement is disabled or completed
RXINV: Receive Polarity Inversion bit
1 = UxRX Idle state is ‘0’
0 = UxRX Idle state is ‘1’
Note 1: This feature is only available for the 16x BRG mode (BRGH = 0).
2: Bit availability depends on pin availability.
