MSCAN08 Controller (MSCAN08)
CLKSRC — Clock Source
This flag defines which clock source the MSCAN08 module is driven
from (see Clock System on page 342).
1 = The MSCAN08 clock source is CGMOUT (see Figure 20-7).
0 = The MSCAN08 clock source is CGMXCLK/2 (see Figure 20-7).
NOTE: The CMCR1 register can be written only if the SFTRES bit in the
MSCAN08 module control register is set

SJW1 and SJW0 — Synchronization Jump Width
The synchronization jump width (SJW) defines the maximum number
of time quanta (T_q) clock cycles by which a bit may be shortened, or
lengthened, to achieve resynchronization on data transitions on the
bus (see Table 20-6).
