enabling the UART module for receive or transmit operation.
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
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
1 = IrDA
0 = IrDA
RTSMD: Mode Selection for UxRTS Pin bit
1 = UxRTS pin in Simplex mode
0 = UxRTS pin in Flow Control mode
Unimplemented: Read as ‘0’
UEN<1:0>: UARTx Enable bits
11 = UxTX, UxRX and BCLK pins are enabled and used; UxCTS pin 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 controlled by port latches
00 = UxTX and UxRX pins are enabled and used; UxCTS and UxRTS/BCLK pins controlled by
WAKE: Wake-up on Start bit Detect During Sleep Mode Enable bit
1 = UARTx continues to sample the UxRX pin; interrupt generated on falling edge; bit cleared
0 = No wake-up 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)
0 = Baud rate measurement disabled or completed
