Bit 7—Transmit Data Register Empty (TDRE): Indicates that the SCI has loaded transmit data
from TDR into TSR and the next serial data can be written in TDR.
Bit 7
TDRE
0
1
Bit 6—Receive Data Register Full (RDRF): Indicates that RDR contains new receive data.
Bit 6
RDRF
0
1
Note: The RDR contents and the RDRF flag are not affected by detection of receive errors or by
clearing of the RE bit to 0 in SCR. They retain their previous values. If the RDRF flag is
still set to 1 when reception of the next data ends, an overrun error will occur and the
receive data will be lost.
Description
TDR contains valid transmit data
[Clearing condition]
Read TDRE when TDRE = 1, then write 0 in TDRE
TDR does not contain valid transmit data
[Setting conditions]
Description
RDR does not contain new receive data
[Clearing conditions]
RDR contains new receive data
[Setting condition]
Serial data is received normally and transferred from RSR to RDR
The chip is reset or enters standby mode
The TE bit in SCR is cleared to 0
TDR contents are loaded into TSR, so new data can be written in TDR
The chip is reset or enters standby mode
Read RDRF when RDRF = 1, then write 0 in RDRF
