LINSCI clock tolerance
LINSCI clock tolerance when unsynchronized
When LIN slaves are unsynchronized (meaning no characters have been transmitted for a
relatively long time), the maximum tolerated deviation of the LINSCI clock is +/-15%.
If the deviation is within this range then the LIN synch break is detected properly when a
new reception occurs.
This is made possible by the fact that masters send 13 low bits for the LIN synch break,
which can be interpreted as 11 low bits (13 bits -15% = 11.05) by a “fast” slave and then
considered as a LIN synch break. According to the LIN specification, a LIN synch break is
valid when its duration is greater than t
must last at least 11 low bits.
