SCDR consists of two data registers located at the same address. The receive data
register (RDR) is a read-only register that contains data received by the SCI serial in-
terface. Data comes into the receive serial shifter and is transferred to RDR. The trans-
mit data register (TDR) is a write-only register that contains data to be transmitted.
Data is first written to TDR, then transferred to the transmit serial shifter, where addi-
tional format bits are added before transmission. R[7:0]/T[7:0] contain either the first
eight data bits received when SCDR is read, or the first eight data bits to be transmitted
when SCDR is written. R8/T8 are used when the SCI is configured for nine-bit opera-
tion. When the SCI is configured for 8-bit operation, R8/T8 has no meaning or effect.
PORTQS latches I/O data. Writes drive pins defined as outputs. Reads return data
present on the pins. To avoid driving undefined data, first write a byte to PORTQS,
then configure DDRQS.
0 = No noise detected in the received data.
1 = Noise detected in the received data.
0 = No framing error detected in the received data.
1 = Framing error or break detected in the received data.
0 = No parity error detected in the received data.
1 = Parity error detected in the received data.
