MSCAN08 Controller (MSCAN08)
CLKSRC — Clock Source
12.13.3 MSCAN08 Bus Timing Register 0
SJW1 and SJW0 — Synchronization Jump Width
BRP5–BRP0 — Baud Rate Prescaler

This flag defines which clock source the MSCAN08 module is driven from (see
The synchronization jump width (SJW) defines the maximum number of time quanta (T
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 (T
according to
1 = The MSCAN08 clock source is CGMOUT (see
0 = The MSCAN08 clock source is CGMXCLK/2 (see
Address:
The CMCR1 register can be written only if the SFTRES bit in the MSCAN08
module control register is set
