MCAN bus timing
register 0 (CBT0)
Motorola CAN
MC68HC05X4
NOTE:
Address:
This register can be accessed only when the RR bit in CCNTRL is set.
SJW1, SJW0 — Synchronization jump width bits
BRP5 – BRP0 — Baud rate prescaler bits
Reset:
The synchronization jump width defines the maximum number of
system clock (t
lengthened, to achieve resynchronization on data transitions on the
bus (see
These bits determine the MCAN system clock cycle time (t
is used to build up the individual bit timing, according to
the formula in
