SBK — Send Break
1 = Break frame(s) are transmitted after completion of the current frame
0 = Normal operation
Bits [15:9] — Not Implemented
TDRE — Transmit Data Register Empty Flag
1 = A new character can now be written to register TDR.
0 = Register TDR still contains data to be sent to the transmit serial shifter.
TC — Transmit Complete Flag
1 = SCI transmitter is idle
0 = SCI transmitter is busy
RDRF — Receive Data Register Full Flag
1 = Register RDR contains new data
0 = Register RDR is empty or contains previously read data
RAF — Receiver Active Flag
1 = SCI receiver is busy
0 = SCI receiver is idle
IDLE — Idle-Line Detected Flag
1 = SCI receiver detected an idle-line condition
0 = SCI receiver did not detect an idle-line condition
OR — Overrun Error Flag
1 = RDRF is not cleared before new data arrives
0 = RDRF is cleared before new data arrives
NF — Noise Error Flag
1 = Noise occurred on the received data
0 = No noise detected on the received data
FE — Framing Error Flag
1 = Framing error or break occurred on the received data
0 = No framing error on the received data
PF — Parity Error Flag
1 = Parity error occurred on the received data
0 = No parity error on the received data
SCSR
— SCI Status Register
