UARTEN: UARTx Enable bit⁽¹⁾
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 minimal
Unimplemented: Read as ‘0’
USIDL: UARTx Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
IREN: IrDA^® Encoder and Decoder Enable bit⁽²⁾
1 = IrDA encoder and decoder are enabled
0 = IrDA encoder and decoder are 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’
UEN<1:0>: UARTx Pin Enable bits
11 = UxTX, UxRX and BCLK 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/BCLK 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 is generated on falling edge; bit is cleared
in hardware on following rising edge
0 = No wake-up is enabled
LPBACK: UARTx Loopback Mode Select bit
1 = Enables Loopback mode
0 = Loopback mode is disabled
ABAUD: Auto-Baud Enable bit
1 = Enables baud rate measurement on the next character – requires reception of a Sync field (55h)
before other data; cleared in hardware upon completion
0 = Baud rate measurement is disabled or completed
Note 1:
2:
Refer to Section 17. “UART” (DS70188) in the “dsPIC33F/PIC24H Family Reference Manual” for
information on enabling the UART module for receive or transmit operation. That section of the manual is
available on the Microchip web site, www.microchip.com.
This feature is only available for the 16x BRG mode (BRGH = 0).
