Only 0 can be written for clearing the flags.
Initial
Value R/W
0
R/(W)* Receive Data Ready
Description
Indicates that there are fewer than the receive trigger
set number of data bytes in SCFRDR and no further
data will arrive in asynchronous mode.
0: Reception is in progress or has ended successfully
[Clearing conditions]
•
•
1: No further receive data has arrived
[Setting condition]
When SCFRDR contains fewer than the receive trigger
set number of receive data bytes and no further data
will arrive.*
Note: 1. The DR bit is set 15etu after the last data is
and there is no receive data left in SCFRDR
Power-on reset or manual reset
When all the receive data in SCFRDR has been
read, and 0 is written to DR after reading DR = 1
received at a sampling rate of 1/16 regardless
of the setting of the sampling control bits in
SCSMR.
etu: Elementary time unit (time for transfer of
one bit)
