Section 16 Serial Communication Interface with FIFO (SCIF)
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 number set by
bits RTRG1 and RTRG0 in SCFCR.
0: The number of receive data bytes in SCFRDR is
[Clearing conditions]
•
•
•
1: The number of receive data bytes in SCFRDR is
[Setting condition]
When SCFRDR contains at least the receive trigger
set number of receive data bytes*
Note: * SCFRDR is a 16-byte FIFO register. When
less than the receive trigger set number
equal to or greater than the receive trigger set
number
Power-on reset or manual reset
When SCFRDR is read until the number of
receive data bytes in SCFRDR is less than the
receive trigger set number, and 0 is written to
RDF after reading RDF = 1
When SCFRDR is read by the DMAC until the
number of receive data bytes in SCFRDR is less
than the receive trigger set number
RDF = 1, at least the receive trigger set
number of data bytes can be read. If data is
read when SCFRDR is empty, an undefined
value will be returned. The number of
receive data bytes in SCFRDR is indicated
by the lower bits in SCFDR.
