register (SCRDR).
0: Indicates that no valid received data is stored in SCRDR
[Clearing conditions]

[Setting condition]
When serial reception is completed normally, and received
data is transferred from SCRSR to SCRDR.
Note: In T = 0 mode, when a parity error is detected during
On reset
When data is read from SCRDR
When 0 is written to RDRF
reception, the SCRDR contents and RDRF flag are
unaffected, and the previous state is retained.
On the other hand, in T = 1 mode, when a parity
error is detected during reception, the received data
is transferred to SCRDR, and the RDRF flag is set to
1.
In both T = 0 and T = 1 modes, even if the RE bit in
the serial control register (SCSCR) is cleared to 0,
the SCRDR contents and RDRF flag are unaffected,
and the previous state is retained.
