CLKSRC — Clock Source
The CMCR1 register can be written only if the SFTRES bit in the
MSCAN08 module control register is set

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
lengthened, to achieve resynchronization on data transitions on the
bus (see
1 = The MSCAN08 clock source is CGMOUT (see
0 = The MSCAN08 clock source is CGMXCLK/2 (see
