Description
Transmit Data Register Empty
Indicates whether TDR contains transmit data.
[Setting conditions]

•
[Clearing conditions]
•
•
Receive Data Register Full
Indicates that the received data is stored in RDR.
[Setting condition]
•
[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.
When the TE bit in SCR is 0
When data is transferred from TDR to TSR and data
can be written to TDR
When 0 is written to TDRE after reading TDRE = 1*
When the DTC*
request and writes data to TDR
When serial reception ends normally and receive data
is transferred from RSR to RDR
When 0 is written to RDRF after reading RDRF = 1*
When the DTC*
transfers data from RDR
