Bit Time
SYNC (1 Tq) TSEG1 (4…16 Tq) TSEG2 (2…8 Tq)

Synchronization step width (SJW) = 1…4 Tq

Foralladjustablebaudratesapplies:
t
q
= Base time unit. All segments of the Bit-Timing result in a multiple of this time
unit.
SYNC = Only the edges from recessive to dominant are used for the synchronization.
SJW = Synchronization step width (only for information)
