PF —Parity Error Flag
PF is set if received data has incorrect parity. Clear PF by reading SCSR1 and then reading SCDR.
0 = Parity correct
1 = Incorrect parity detected
Bits [7:1] —Not implemented
Always read zero
RAF —Receiver Active Flag (Read Only)
0 = A character is not being received
1 = A character is being received
R8 —Receiver Bit 8
Ninth serial data bit received when SCI is configured for nine-data-bit operation.
T8 —Transmitter Bit 8
Ninth serial data bit transmitted when SCI is configured for nine-data-bit operation.
Bits [5:0] —Not implemented
Always read zero
R/T[7:0] —Receiver/Transmitter Data Bits [7:0]
SCI data is double buffered in both directions.
