SBK — Send Break
0 = Normal operation
1 = Break frame(s) transmitted after completion of current frame
SBK provides the ability to transmit a break code from the SCI. If the SCI is transmitting when SBK is
set, it will transmit continuous frames of zeros after it completes the current frame, until SBK is cleared.
If SBK is toggled (one to zero in less than one frame interval), the transmitter sends only one or two
break frames before reverting to idle line or beginning to send data.
SCSR contains flags that show SCI operational conditions. These flags can be cleared either by hard-
ware or by a special acknowledgment sequence. The sequence consists of SCSR read with flags set,
followed by SCDR read (write in the case of TDRE and TC). A long-word read can consecutively access
both SCSR and SCDR. This action clears receive status flag bits that were set at the time of the read,
but does not clear TDRE or TC flags.
If an internal SCI signal for setting a status bit comes after the CPU has read the asserted status bits,
but before the CPU has written or read register SCDR, the newly set status bit is not cleared. SCSR
must be read again with the bit set. Also, SCDR must be written or read before the status bit is cleared.
Reading either byte of SCSR causes all 16 bits to be accessed. Any status bit already set in either byte
will be cleared on a subsequent read or write of register SCDR.
TDRE — Transmit Data Register Empty Flag
0 = Register TDR still contains data to be sent to the transmit serial shifter.
1 = A new character can now be written to register TDR.
TDRE is set when the byte in register TDR is transferred to the transmit serial shifter. If TDRE is zero,
transfer has not occurred and a write to TDR will overwrite the previous value. New data is not trans-
mitted if TDR is written without first clearing TDRE.
TC — Transmit Complete Flag
0 = SCI transmitter is busy
1 = SCI transmitter is idle
TC is set when the transmitter finishes shifting out all data, queued preambles (mark/idle line), or
queued breaks (logic zero). The interrupt can be cleared by reading SCSR when TC is set and then by
writing the transmit data register (TDR) of SCDR.
RDRF — Receive Data Register Full Flag
0 = Register RDR is empty or contains previously read data.
1 = Register RDR contains new data.
RDRF is set when the content of the receive serial shifter is transferred to the RDR. If one or more errors
are detected in the received word, flag(s) NF, FE, and/or PF are set within the same clock cycle.
RAF — Receiver Active Flag
0 = SCI receiver is idle
1 = SCI receiver is busy
RAF indicates whether the SCI receiver is busy. It is set when the receiver detects a possible start bit
and is cleared when the chosen type of idle line is detected. RAF can be used to reduce collisions in
systems with multiple masters.
