MC68HC11C0TS/D
TDRE — Transmit Data Register Empty Flag
This flag is set when SCDR is empty. Clear the TDRE flag by reading SCSR and then writing to SCDR.
0 = SCDR busy
1 = SCDR empty
TC — Transmit Complete 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 and then writing to SCDR.
0 = Transmitter busy
1 = Transmitter idle
RDRF — Receive Data Register Full Flag
RDRF is set if a received character is ready to be read from SCDR. Clear the RDRF flag by reading
SCSR and then reading SCDR.
0 = SCDR empty
1 = SCDR full
IDLE — Idle Line Detected Flag
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
and then reading SCDR.
0 = RxD line is active
1 = RxD line is idle
OR — Overrun Error Flag
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 and then reading SCDR.
0 = No overrun
1 = Overrun detected
NF — Noise Error Flag
NF is set if majority sample logic detects anything other than a unanimous decision. Clear NF by reading
SCSR and then reading SCDR.
0 = Unanimous decision
1 = Noise detected
FE — Framing Error
FE is set when a zero is detected where a stop bit was expected. Clear the FE flag by reading SCSR
and then reading SCDR.
0 = Stop bit detected
1 = Zero detected
Bit 0 — Not implemented
Always reads zero
SCSR — SCI Status Register
