By a power-on reset or in standby mode
When 0 is written to RDRF after reading RDRF =
1
When the DTC is activated by an RXI interrupt
and data is transferred from SCRDR while the
DISEL bit of MRB in the DTC is 0
When serial reception ends normally and receive
data is transferred from SCRSR to SCRDR
retain their previous states even if an error is
detected during data reception or if the RE bit in
the serial control register (SCSCR) 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 received data will be
