Description
This bit is reset to 0 when the UARTx_RBR register is read or
all bytes are read from the receiver FIFO.
Data ready. If the FIFO is not enabled, this bit is set to 1 when
a complete incoming character is transferred into the receiver
buffer register from the receiver shift register. If the FIFO is
enabled, this bit is set to 1 when a character is received and
transferred to the receiver FIFO.
Description
Data Carrier Detect
In NORMAL mode, this bit reflects the inverted state of the
DCDx input pin. In LOOP BACK mode, this bit reflects the
value of the UARTx_MCTL[3] = out2.
Ring Indicator
In NORMAL mode, this bit reflects the inverted state of the RIx
input pin. In LOOP BACK mode, this bit reflects the value of the
UARTx_MCTL[2] = out1.
Data Set Ready
In NORMAL mode, this bit reflects the inverted state of the
DSRx input pin. In LOOP BACK mode, this bit reflects the
value of the UARTx_MCTL[0] = DTR.
Clear to Send
In NORMAL mode, this bit reflects the inverted state of the
CTSx input pin. In LOOP BACK mode, this bit reflects the value
of the UARTx_MCTL[1] = RTS.
