MOTOROLA
TDRE — Transmit Data Register Empty Flag
TC — Transmit Complete Flag
RDRF — Receive Data Register Full Flag
IDLE — Idle Line Detected Flag
OR — Overrun Error Flag
NF — Noise Error Flag
TDRE is set when the SCDR transfers its contents to the transmission
shift register.
TC is set when the final character in a message has been sent (no
data, preamble, or break transmissions pending).
RDRF is set when the shift register has received a complete character
and transferred it to the receive data register.
IDLE is set when a frame of all 1s is received after a message.
OR is set if a new character is received before a previously received
character is read from SCDR.
NF is set after the last bit in a frame is received if the samples in the
receiver’s data recovery circuit are not unanimous for any of the bits,
including start and stop bits.
