R/W
R/(W)* Receive Data Register Full
Description
Indicates that the received data is stored in the
receive data register (SCRDR).
0: Indicates that valid received data is not stored in
[Clearing conditions]
•
•
1: Indicates that valid received data is stored in
[Setting condition]
•
Note: SCRDR and the RDRF flag are not affected and
SCRDR
SCRDR
By a power-on reset or in standby mode
When 0 is written to RDRF after reading RDRF =
1
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
lost.
