UTXINV: IrDA Encoder Transmit Polarity Inversion bit
1 = IrDA encoded U1TX idle state is ‘1’
0 = IrDA encoded U1TX idle state is ‘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 disabled or completed
UTXEN: Transmit Enable bit
1 = Transmit enabled, U1TX pin controlled by UART1
0 = Transmit disabled, any pending transmission is aborted and buffer is reset. U1TX pin controlled by
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
0 = Transmit Shift Register is not empty, a transmission is in progress or queued
URXISEL1:URXISEL0: Receive Interrupt Mode Selection bits
11 =Interrupt is set on RSR transfer, making the receive buffer full (i.e., has 4 data characters)
10 =Interrupt is set on RSR 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 RSR to the receive buffer.
ADDEN: Address Character Detect bit (bit 8 of received data = 1)
1 = Address Detect mode enabled. If 9-bit mode is not selected, this does not take effect.
0 = Address Detect mode disabled
