R = Readable bit
-n = Value at POR
HC = Hardware Clearable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown

UARTEN: UART1 Enable bit^(1,3)
1 = UART1 is enabled; all UART1 pins are controlled by UART1, as defined by UEN<1:0>
0 = UART1 is disabled; all UART1 pins are controlled by port latches; UART1 power consumption
is minimal
Unimplemented: Read as ‘0’
USIDL: Stop in Idle Mode bit⁽³⁾
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
IREN: IrDA^® Encoder and Decoder Enable bit^(2,3)
1 = IrDA^® encoder and decoder are enabled
0 = IrDA^® encoder and decoder are disabled
RTSMD: Mode Selection for U1RTS Pin bit⁽³⁾
1 = U1RTS pin is in Simplex mode
0 = U1RTS pin is in Flow Control mode
Unimplemented: Read as ‘0’
UEN<1:0>: UART1 Pin Enable bits⁽³⁾
11 = U1TX, U1RX and BCLK pins are enabled and used; U1CTS pin is controlled by port latches
10 = U1TX, U1RX, U1CTS and U1RTS pins are enabled and used
01 = U1TX, U1RX and U1RTS pins are enabled and used; U1CTS pin is controlled by port latches
00 = U1TX and U1RX pins are enabled and used; U1CTS and U1RTS/BCLK pins are controlled by
port latches
WAKE: Wake-up on Start bit Detect During Sleep Mode Enable bit⁽³⁾
1 = UART1 will continue to sample the U1RX pin; interrupt is generated on falling edge; bit is cleared
in hardware on following rising edge
0 = No wake-up is enabled
LPBACK: UART1 Loopback Mode Select bit⁽³⁾
1 = Enable Loopback mode
0 = Loopback mode is disabled
ABAUD: Auto-Baud Enable bit⁽³⁾
1 = Enable baud rate measurement on the next character – requires reception of a Sync field (0x55)
before other data; cleared in hardware upon completion
0 = Baud rate measurement is disabled or completed

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.
This feature is only available for the 16x BRG mode (BRGH = 0).
This bit is not available in the dsPIC33FJ06GS001 device.
