NOTE:
Calculation of the bit time
TSEG2 must be at least 2 t
000. (If three samples per bit mode is selected then TSEG2 must be at
least 3 t
TSEG1 must be at least as long as TSEG2.
The synchronization jump width (SJW) may not exceed TSEG2, and
must be at least t
propagation delays.
i.e. in terms of t
These boundary conditions result in minimum bit times of 5 t
sample, and 7 t
