RFIFO Threshold Level
The size of the accessible part of RFIFO can be determined by
programming these bits. The number of valid bytes after an
RPF interrupt is given in the following table:
The value of RFT1,0 can be changed dynamically
– if reception is not running (recommended: receiver is disabled
– after RME interrupt has been generated, but before the
– after the current data block has been read, but before the
Note: It is seen that changing the value of RFT1, 0 is possible

even during the reception of one frame. The total length of
the received frame can be always read directly in RBCL,
RBCH after an RPF interrupt, except when the threshold is
increased during reception of that frame. The real length
can then be inferred by noting which bit positions in RBCL
are reset by an RMC command (see table below):
