Bit Bit
Name
Initial
Value R/W
Description
0 DR 0 R/W
*
Receive
Data
Ready
In asynchronous mode, indicates that there are fewer
than the receive trigger set number of data bytes in
SCFRDR, and no further data has arrived for at least
15 etu after the stop bit of the last data received. This is
not set when using clocked synchronous mode.
0: Reception is in progress or has ended normally and
there is no receive data left in SCFRDR
[Clearing conditions]
•
Power-on reset or manual reset
•
When all the receive data in SCFRDR has been
read after reading DR = 1, and 0 is written to DR
•
When all the receive data in SCFRDR has been
read by the DMAC
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 has arrived for at least 15 etu after the
stop bit of the last data received
*
[Legend] etu: Elementary time unit (time for transfer of
1 bit)
Note: Equivalent to 1.5 frames with an 8-bit, 1-stop-bit
format.
Note:
*
Only 0 can be written, to clear the flag.
