Description
1 RDF 0 R/W
*
Receive FIFO Data Full
Indicates that the received data has been transferred
from SCRSR to SCFRDR, and the number of receive
data bytes in SCFRDR is equal to or greater than the
receive trigger number set by bits RTRG1 and RTRG0
in SCFCR.
0: The number of receive data bytes in SCFRDR is less
than the receive trigger set number
[Clearing conditions]
•
Power-on reset or manual reset
•
When SCFRDR is read until the number of receive
data bytes in SCFRDR falls below the receive
trigger set number after reading RDF = 1, and 0 is
written to RDF
•
When SCFRDR is read by the DMAC until the
number of receive data bytes in SCFRDR falls
below the receive trigger set number
1: The number of receive data bytes in SCFRDR is
equal to or greater than the receive trigger set
number
[Setting condition]
•
When SCFRDR contains at least the receive trigger
set number of receive data bytes
*
Note: SCFRDR is a 64-byte FIFO register. When RDF
= 1, at least the receive trigger set number of
data bytes can be read. If all the data in
SCFRDR is read and another read is performed,
the data value will be undefined. The number of
receive data bytes in SCFRDR is indicated by
SCRFDR.
