Number of Preamble Repetitions
If preamble transmission is enabled, the preamble defined by register
PRE is transmitted:
00... 1 time
01... 2 times
10... 4 times
11... 8 times
Enable Preamble Transmission
This bit enables transmission of preamble. The preamble is started
after interframe timefill transmission has been stopped and a new
frame is to be transmitted. The preamble consists of an 8-bit pattern
repeated a number of times. The pattern is defined by register PRE,
the number of repetitions is selected by bits PRE0 and PRE1.

during the reception of one frame. The total length of the
received frame can be always read directly in RBCL, RBCH
after a 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 a
RMC command (see table below):
