URXISEL<1:0> ADDEN RIDLE PERR FERR OERR URXDA
bit 7 bit 0
Legend: HC = Hardware cleared C = Clearable bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15,13 UTXISEL<1:0>: Transmission Interrupt Mode Selection bits
11 = Reserved; do not use
10 = Interrupt when a character is transferred to the Transmit Shift Register, and as a result, the
transmit buffer becomes empty
01 = Interrupt when the last character is shifted out of the Transmit Shift Register; all transmit
operations are completed
00 = Interrupt when a character is transferred to the Transmit Shift Register (this implies there is
at least one character open in the transmit buffer)
bit 14 UTXINV: Transmit Polarity Inversion bit
If IREN =
0:
1 = UxTX Idle state is ‘0’
0 = UxTX Idle state is ‘1’
If IREN =
1:
1 = IrDA
®
encoded UxTX Idle state is ‘1’
0 = IrDA encoded UxTX Idle state is ‘0’
bit 12 Unimplemented: Read as ‘0’
bit 11 UTXBRK: Transmit Break bit
1 = Send Sync Break on next transmission – Start bit, followed by twelve ‘0’ bits, followed by Stop bit;
cleared by hardware upon completion
0 = Sync Break transmission disabled or completed
bit 10 UTXEN: Transmit Enable bit
(1)
1 = Transmit enabled, UxTX pin controlled by UARTx
0 = Transmit disabled, any pending transmission is aborted and buffer is reset. UxTX pin controlled
by port.
bit 9 UTXBF: Transmit Buffer Full Status bit (read-only)
1 = Transmit buffer is full
0 = Transmit buffer is not full, at least one more character can be written
bit 8 TRMT: Transmit Shift Register Empty bit (read-only)
1 = Transmit Shift Register is empty and transmit buffer is empty (the last transmission has completed)
0 = Transmit Shift Register is not empty, a transmission is in progress or queued
bit 7-6 URXISEL<1:0>: Receive Interrupt Mode Selection bits
11 = Interrupt is set on UxRSR transfer making the receive buffer full (i.e., has 4 data characters)
10 = Interrupt is set on UxRSR transfer making the receive buffer 3/4 full (i.e., has 3 data characters)
0x = Interrupt is set when any character is received and transferred from the UxRSR to the receive
buffer. Receive buffer has one or more characters.
Note 1: Refer to Section 21. “UART” (DS39708) in the “PIC24F Family Reference Manual” for information on
enabling the UART module for transmit operation.
