Bit 1—Receive FIFO Data Full (RDF): Indicates that the received data has been transferred
from SCRSR2 to SCFRDR2, and the number of receive data bytes in SCFRDR2 is equal to or
greater than the receive trigger number set by bits RTRG1 and RTRG0 in the FIFO control
register (SCFCR2).
Bit 1: RDF
0
1
Note:
*
SCFRDR2 is a 16-byte FIFO register. When RDF = 1, at least the receive trigger set
number of data bytes can be read. If all the data in SCFRDR2 is read and another read
is performed, the data value will be undefined. The number of receive data bytes in
SCFRDR2 is indicated by the lower bits of SCFDR2.
Description
The number of receive data bytes in SCFRDR2 is less than the receive
trigger set number
[Clearing conditions]

•
•
The number of receive data bytes in SCFRDR2 is equal to or greater than
the receive trigger set number
[Setting condition]
When SCFRDR2 contains at least the receive trigger set number of receive
data bytes*
Power-on reset or manual reset
When SCFRDR2 is read until the number of receive data bytes in
SCFRDR2 falls below the receive trigger set number after reading RDF
= 1, and 0 is written to RDF
When SCFRDR2 is read by the DMAC until the number of receive data
bytes in SCFRDR2 falls below the receive trigger set number
