Section 15 Serial Communication Interface (SCI)
Bit 7—Transmit Data Register Empty (TDRE): Indicates that data has been transferred from
SCTDR1 to SCTSR1 and the next serial transmit data can be written to SCTDR1.
Bit 7: TDRE
0
1
Bit 6—Receive Data Register Full (RDRF): Indicates that the received data has been stored in
SCRDR1.
Bit 6: RDRF
0
1
Note: SCRDR1 and the RDRF flag are not affected and retain their previous values when an error

is detected during reception or when the RE bit in SCSCR1 is cleared to 0.
If reception of the next data is completed while the RDRF flag is still set to 1, an overrun
error will occur and the receive data will be lost.
