Description
Transmit Data Register Empty
Indicates whether TDR contains transmit data.

•
[Clearing conditions]
•
•
Receive Data Register Full
Indicates that the received data is stored in RDR.
[Setting condition]
When serial reception ends normally and receive
data is transferred from RSR to RDR
[Clearing conditions]
•
•
The RDRF flag is not affected and retains their
previous values when the RE bit in SCR 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.
