TC — Transmit Complete Flag
RDRF — Receive Data Register Full Flag
IDLE — Idle Line Detected Flag
OR — Overrun Error Flag
NF — Noise Error Flag
This flag is set when the transmitter is idle (no data, preamble, or
break transmission in progress). Clear the TC flag by reading SCSR
with TC set and then writing to SCDR.
This flag is set if a received character is ready to be read from SCDR.
Clear the RDRF flag by reading SCSR with RDRF set and then
reading SCDR.
This flag is set if the RxD line is idle. Once cleared, IDLE is not set
again until the RxD line has been active and becomes idle again. The
IDLE flag is inhibited when RWU = 1. Clear IDLE by reading SCSR
with IDLE set and then reading SCDR.
OR is set if a new character is received before a previously received
character is read from SCDR. Clear the OR flag by reading SCSR
with OR set and then reading SCDR.
NF is set if majority sample logic detects anything other than a
unanimous decision. Clear NF by reading SCSR with NF set and then
reading SCDR.
0 = Transmitter busy
1 = Transmitter idle
0 = SCDR empty
1 = SCDR full
0 = RxD line active
1 = RxD line idle
0 = No overrun
1 = Overrun detected
0 = Unanimous decision
1 = Noise detected
