[Clearing conditions]
•
The RDRF flag is not affected and retains its
previous value even if the RE bit in SCR is cleared
to 0.
When the TE bit in SCR is 0
When data is transferred from TDR to TSR
and TDR is ready for data write
When 0 is written to TDRE after reading TDRE
= 1
When serial reception ends normally and
receive data is transferred from RSR to RDR
When 0 is written to RDRF after reading RDRF
= 1
