Description
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 count set by the RTRG1 and RTRG0
bits in SCFCR.
0: The number of receive data bytes in SCFRDR is less

Power-on reset or manual reset
When SCFRDR is read until the number of receive
data bytes in SCFRDR falls below the receive
trigger setting count 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 setting count
When SCFRDR contains at least the receive trigger
setting count of receive data bytes*
