Description
No function in normal operation.
In LOOP BACK mode, this bit is connected to the DCD bit in the UART Status
Register.
No function in normal operation.
In LOOP BACK mode, this bit is connected to the RI bit in the UART Status
Register.
Request to Send.
In normal operation, the RTS output port is the inverse of this bit. In LOOP
BACK mode, this bit is connected to the CTS bit in the UART Status Register.
Data Terminal Ready.
In normal operation, the DTR output port is the inverse of this bit. In LOOP
BACK mode, this bit is connected to the DSR bit in the UART Status Register.
Description
Always 0 when operating in with the FIFO disabled. With the
FIFO enabled, this bit is reset when the UARTx_LSR register is
read and there are no more bytes with error status in the FIFO.
Error detected in the FIFO. There is at least 1 parity, framing or
break indication error in the FIFO.
Transmit holding register/FIFO is not empty or transmit shift
register is not empty or transmitter is not idle.
Transmit holding register/FIFO and transmit shift register are
empty; and the transmitter is idle. This bit cannot be set to 1
during the BREAK condition. This bit only becomes 1 after the
BREAK command is removed.
