SYNCH — Synchronized status
This bit indicates whether the msCAN08 is synchronized to the CAN
bus and as such can participate in the communication process.
1 = msCAN08 is synchronized to the CAN bus
0 = msCAN08 is not synchronized to the CAN bus
TLNKEN — Timer enable
This flag is used to establish a link between the msCAN08 and the
on-chip timer (see Timer link on page 370).
1 = The msCAN08 timer signal output is connected to the timer.
0 = No connection.
