(1)
If UARTEN = 1, the peripheral inputs and outputs must be configured to an available RPn pin.
See Section 9.4 “Peripheral Pin Select” for more information.
This feature is only available for the 16x BRG mode (BRGH = 0).
UARTEN: UARTx Enable bit
1 = UARTx is enabled; all UARTx pins are controlled by UARTx as defined by UEN1:UEN0
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 encoder and decoder enabled
0 = IrDA encoder and decoder disabled
RTSMD: Mode Selection for UxRTS Pin bit
1 = UxRTS pin in Simplex mode
0 = UxRTS pin in Flow Control mode
Unimplemented: Read as ‘0’
UEN1:UEN0: UARTx Enable bits
11 = UxTX, UxRX and BCLKx 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/BCLKx pins controlled by PORT
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 cleared in
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
