The value of the bit only affects the transmit properties of the module when the IrDA
(IREN = 1).
If UARTEN = 1, the peripheral inputs and outputs must be configured to an available RPn/RPIn pin. See
Section 11.4 “Peripheral Pin Select (PPS)”
The TRMT bit will be active only after two instruction, cycles once the UTXREG is loaded.
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 (TSR), and as a result, the
01 = Interrupt when the last character is shifted out of the Transmit Shift Register; all transmit
00 = Interrupt when a character is transferred to the Transmit Shift Register (this implies there is at least
UTXINV: IrDA
IREN = 0:
1 = UxTX is Idle ‘0’
0 = UxTX is Idle ‘1’
IREN = 1:
1 = UxTX is Idle ‘1’
0 = UxTX is Idle ‘0’
Unimplemented: Read as ‘0’
UTXBRK: Transmit Break bit
1 = Send Sync Break on next transmission – Start bit, followed by twelve ‘0’ bits, followed by Stop bit;
0 = Sync Break transmission is disabled or completed
UTXEN: Transmit Enable bit
1 = Transmit is enabled, UxTX pin is controlled by UARTx
0 = Transmit is disabled, any pending transmission is aborted and the buffer is reset; UxTX pin is
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
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
