SJW1, SJW0 — Synchronization Jump Width
BRP5 – BRP0 — Baud Rate Prescaler
The CBTR0 register can only be written if the SFTRES bit in CMCR0 is
set.
SJW0
The synchronization jump width defines the maximum number of time
quanta (Tq) clock cycles by which a bit may be shortened, or
lengthened, to achieve resynchronization on data transitions on the
bus (see
These bits determine the time quanta (Tq) clock, which is used to
build up the individual bit timing, according to
