bit 9-8
bit 7
Reserved: Write ‘0’; ignore read
ON: UARTx Enable bit
1 = UARTx is enabled; UARTx pins are controlled by UARTx as defined by UEN<1:0> and UTXEN
control bits
0 = UARTx is disabled, all UARTx pins are controlled by corresponding PORT TRIS and LAT bits;
UARTx power consumption is minimal
FRZ: Freeze in Debug Exception Mode bit
1 = Freeze operation when CPU is in Debug Exception mode
0 = Continue operation when CPU is in Debug Exception mode
Note: ^. FRZ is writable in Debug Exception mode only, it is forced to ‘0’ in normal mode.
SIDL: Stop in Idle Mode bit
1 = Discontinue operation when device enters in Idle mode
0 = Continue operation in Idle mode
IREN: IrDA Encoder and Decoder Enable bit
1 = IrDA is enabled
0 = IrDA is 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
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: Enable Wake-up on Start bit Detect During Sleep mode bit
1 = Wake-up enabled
0 = Wake-up disabled
