SCDR consists of two data registers located at the same address. RDR is a read-only
register that contains data received by the SCI serial interface. Data comes into the
receive serial shifter and is transferred to RDR. TDR is a write-only register that con-
tains data to be transmitted. Data is first written to TDR, then transferred to the transmit
serial shifter, where additional 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 con-
figured for nine-bit operation. When the SCI is configured for eight-bit operation, R8/
T8 have 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.
Clearing a bit in PQSPAR assigns the corresponding pin to general-purpose I/O; set-
ting a bit assigns the pin to the QSPI. PQSPAR does not affect operation of the SCI.

RESET:
0 = No parity error on the received data
1 = Parity error occurred on the received data.
